About this book

Thomas Watson's The Ten Commandments is a classic Puritan work that offers a profound and practical study of the moral law as presented in the Ten Commandments. Written in the 17th century, Watson's book addresses not only the external behaviors governed by the commandments but also their deeper spiritual and moral significance. His reflections guide the reader to understand that the law reveals both God's character and human sinfulness, leading believers to a life of repentance and obedience through the grace of Christ.

Watson begins by discussing the purpose and significance of God's law. He emphasizes that the Ten Commandments serve as a mirror, reflecting human sin and showing the need for salvation through Christ. The law, Watson argues, is not merely a set of rules but a guide to living a holy life, a tool for sanctification. While the commandments cannot save, they drive the believer to Christ, who fulfills the law on behalf of sinners.

The First Table (Commandments 1-4) focuses on the believer's relationship with God. Watson carefully unpacks the call to worship God alone, reject idolatry, honor God's name, and observe the Sabbath. He stresses that these commandments are foundational to a life of faith because they set the parameters for loving and serving God properly.

The Second Table (Commandments 5-10) regulates human relationships. Watson explains how honoring parents, refraining from murder, adultery, theft, false witness, and covetousness reflects the love of neighbor. Each commandment is explored not only in terms of outward action but also in terms of the attitudes and intentions behind those actions.

Throughout the book, Watson provides practical advice for how Christians can avoid sin and pursue a life of holiness. He offers strategies for resisting temptation, cultivating godly habits, and growing in love for God and neighbor. Watson makes clear that while the Ten Commandments reveal human sin, they also point believers to Christ, the only one who perfectly fulfilled the law.

Watson closes by emphasizing that true obedience to the commandments flows from a heart transformed by God's grace. While believers will never perfectly keep the law, they are called to pursue holiness with the help of the Holy Spirit. Obedience, for Watson, is a response of love toward God, not a means of earning salvation.

Obedience to God's Revealed Will

(Deut 27:9–10) “Take heed and hearken, O Israel, this day thou art become the people of the Lord thy God; thou shalt therefore obey the voice of the Lord thy God, and do his commandments.”

Question 39: What is the duty that God requires of man?

Answer: Obedience to his revealed will.

It is not enough to hear God's voice; we must obey. Obedience is part of the honor we owe to God. (Mal 1:6) asks, "If I be a Father, where is my honour?" Obedience carries in it the lifeblood of religion: "Obey the voice of the Lord God, and do his commandments." Obedience without knowledge is blind, and knowledge without obedience is lame. Rachel was fair to look upon, but, being barren, said, "Give me children, or I die." So it is with knowledge: if it does not bring forth the child of obedience, it will die. As 1 Samuel 15:22 says, "To obey is better than sacrifice." Saul thought it enough to offer sacrifices, even while disobeying God's command, but no, "to obey is better than sacrifice." God disowns sacrifice where obedience is lacking: (Jer 7:22), "I spake not to your fathers concerning burnt-offerings, but this thing commanded I them, saying, obey my voice."

This does not mean God never required those religious rites of worship, but rather that God looked chiefly at obedience, without which sacrifice was mere devout folly. The purpose for which God gave us his laws is obedience: (Lev 18:4), "Ye shall do my judgments, and keep my ordinances." Why does a king publish an edict, except that it be observed?

Question 1: What is the rule of obedience?

Answer: The written word. True obedience is what the word requires; our obedience must correspond to the word as a copy corresponds to its original. To appear zealous in a way not grounded in the word is not obedience but self-devised worship. Popish traditions, which have no footing in the word, are abominable, and God will say, "Who hath required this at your hand?" (Isa 1:12). The apostle condemns the worship of angels, which had the appearance of humility (Col 2:18). The Jews might claim they were too humble to come to God directly in their own persons, that it seemed more fitting to prostrate themselves before angels and ask the angels to present their petitions to God. But this show of humility was hateful to God, because there was no word to warrant it.

Question 2: What are the right ingredients in our obedience that make it acceptable? How must it be qualified?

Answer 1: Obedience must be offered with a willing spirit, free and cheerful, or else it is penance, not sacrifice. As Isaiah 1:19 says, "If ye be willing and obedient." Though we serve God with weakness, let it be with willingness. You love to see your own servants go cheerfully about your work. Under the law, God desired "a free-will offering" (Deut 16:10). Hypocrites obey God grudgingly and against their will; they do the good deed but do not truly will it. Cain brought his sacrifice, but not his heart. It is a true rule: whatever the heart does not do is not truly done. Willingness is the soul of obedience. God sometimes accepts willingness without the completed work, but never the work without willingness. Cheerfulness shows that love is present in the duty, and love does for our services what the sun does for fruit, it ripens and mellows them, giving them a better flavor.

Answer 2: Obedience must be devout and fervent. As Romans 12:11 says, "Fervent in spirit," and so on. The image is of water boiling over from heat, so the heart must boil over with warm affections in the service of God. The glorious angels, called Seraphim for their burning fervor and devotion, are the ones God chooses to serve him in heaven. The snail was reckoned unclean under the law, being a dull and slothful creature. Obedience without fervency is like a sacrifice without fire. Why should not our obedience be lively and fervent? God deserves the very flower and strength of our affections. Domitian would not have his statue carved in wood or iron, but in gold, so lively affections make golden acts of service. It is fervency that makes obedience acceptable.

Elijah was fervent in spirit, and his prayer opened and shut heaven; and again he prayed, and fire fell on his enemies (2 Kgs 1:10). Elijah's prayer brought down fire from heaven because, being fervent, it carried fire up to heaven, for, as Augustine says, whatever grace produces through faith comes with true beauty.

Answer 3: Obedience must be extensive, it must reach to all God's commands: “Then shall I not be ashamed, when I have respect unto all thy commandments” (Ps 119:6). Whatever is done for God's sake must be done with equal regard to all his commands. There is a stamp of divine authority upon every one of God's commands; and if I obey one precept because God commands it, I must obey them all. True obedience runs through all the duties of religion, as blood runs through all the veins, or as the sun passes through all the signs of the zodiac. A good Christian makes gospel piety and moral integrity kiss each other. Here some betray their hypocrisy: they will obey God in matters that are easier and may enhance their reputation, but leave other things undone.

“One thing thou lackest” (Mark 10:21), one thing is missing. Herod would listen to John the Baptist but would not give up his incest; some will pray but not give alms, others will give alms but not pray: “Ye pay tithe of mint and anise, and have omitted the weightier matters of the law, judgment, mercy, and faith” (Matt 23:23). The badger has one foot shorter than the other; so these people fall short in some duties while keeping up others. God has no regard for such partial servants, who do part of the work he sets them to and leave the rest undone.

Answer 4: Obedience must be sincere, that is, we must aim at the glory of God in it. The end determines the nature of the action; in religion, the end is everything. The purpose of our obedience must not be to silence conscience, or to win applause or advancement, but to grow more like God and bring him greater glory: “Do all to the glory of God” (1 Cor 10:31). What has ruined many otherwise glorious actions, and cost them their reward, is a wrong aim. The Pharisees gave alms but sounded a trumpet so that they might have glory from men (Matt 6:2); alms should shine, but not blaze. Jehu did well in destroying the worshippers of Baal, and God commended him for it; but because his aims were not good, he was really securing the kingdom for himself, God regarded it as no better than murder: “I will avenge the blood of Jezreel upon the house of Jehu” (Hos 1:4). Let us examine our ends in obedience!

It is possible for the action to be right while the heart is not: “Joash did that which was right in the sight of the Lord,” but not with a perfect heart (2 Chr 25:2). Two things above all must be watched in obedience: the principle and the end. A child of God, though he falls short in his obedience, nevertheless takes true aim.

Answer 5: Obedience must be offered in and through Christ: “He hath made us accepted in the beloved” (Eph 1:6). It is not our obedience but Christ's merits that secure acceptance with God; in every act of worship we must present Christ to God in the arms of our faith. Unless we serve God in this way, trusting in the merits of Christ, we provoke him rather than please him. When King Uzziah presumed to offer incense without a priest, God was angry with him and struck him with leprosy (2 Chr 26:16). In the same way, when we come to God apart from Christ, we offer incense without a priest, and we can expect nothing but severe rebuke.

Answer 6: Obedience must be constant: “Blessed is he that doeth righteousness at all times” (Ps 106:3). True obedience is not like a flush of color that comes and goes with a passing fit; it is a lasting, healthy complexion. It is like the fire on the altar, which was kept burning continually (Lev 6:13). The obedience of hypocrites lasts only for a season; it is like plaster-work, soon washed away. But true obedience holds steady: even when we meet affliction, we must continue in it. “The righteous also shall hold on his way” (Job 17:9). We have vowed constancy; we have vowed to renounce the pomp and vanities of the world and to fight under Christ's banner until death. When a servant has entered into covenant with his master and the papers are sealed, he cannot turn back, he must serve out his time. Such an agreement is drawn up in baptism, and at the Lord's Supper it is renewed and sealed again on our part, pledging that we will be faithful and constant in our obedience.

So we must follow the example of Christ, who “became obedient unto death” (Phil 2:8). The crown is set on the head of perseverance: “He that keepeth my works unto the end, to him will I give... the morning star” (Rev 2:26, 28).

Application 1. This indicts those who live in contradiction to this text: they have cast off the yoke of obedience. Jeremiah 44:16 says, “As for the word which thou hast spoken to us in the name of the Lord, we will not hearken unto thee.” God bids men pray in their family, they live in total neglect of it. He bids them sanctify the sabbath, they follow their pleasures on that day. God bids them abstain from the appearance of sin, they do not even abstain from the act; they live in the act of revenge, in the act of uncleanness. This is a high contempt of God; it is rebellion. And rebellion is as the sin of witchcraft.

Question: Why is it that men do not obey God, when they know their duty yet fail to do it?

Answer: First, failing to obey God comes from a lack of faith. (Isa 53:1) asks, “Who hath believed our report?” If men believed that sin were so bitter that hell followed at its heels, would they go on in sin? If they believed there were such a reward for the righteous that godliness were gain, would they not pursue it? But they are atheists at heart, not fully persuaded of these truths, and that is why they do not obey. This is Satan's masterpiece, his dragnet by which he drags millions to hell: he keeps them in unbelief, knowing that if he can keep them from believing the truth, he is sure to keep them from obeying it.

Answer: Second, failing to obey God comes from a lack of self-denial. God commands one thing, and men's lusts command another, and they will rather die than deny their lusts. If lust cannot be denied, God cannot be obeyed.

Application 2. Obey God's voice. This is the beauty of a Christian.

Question: What are the great arguments or incentives to obedience?

Answer: First, obedience makes us precious to God; we become his favorites. Exodus 19:5 says, “If ye will obey my voice, ye shall be a peculiar treasure to me above all people,” you shall be my portion, my jewels, the apple of my eye. “I will give Egypt for thy ransom” (Isa 43:3).

Answer: Second, nothing is lost by obedience. To obey God's will is the way to have our own will fulfilled.

1.) If we would have a blessing on our estates, let us obey. Deuteronomy 28:1, 3 says, "If thou shalt hearken to the voice of the Lord, to do all his commandments, blessed shalt thou be in the field: blessed shalt be thy basket and thy store." To obey is the best way to thrive in our estates.

2.) If we would have a blessing on our souls, let us obey. Jeremiah 7:23 says, "Obey my voice, and I will be your God." My Spirit shall be your guide, sanctifier, and comforter. Hebrews 5:9 says, "Christ became the author of eternal salvation to all them that obey him." While we please God, we please ourselves; while we give him our duty, he gives us the dowry. We are apt to say, as Amaziah did, (2 Chr 25:9), "What shall we do for the hundred talents?" But you see you lose nothing by obeying; the obedient son has the inheritance settled on him. Obey, and you shall have a kingdom. Luke 12:32 says, "It is your Father's good pleasure to give you the kingdom."

Application 3. Consider what a sin disobedience is.

1. It is an irrational sin.

1.) We are not able to stand our ground in defiance against God. (1 Cor 10:22) asks, "Are we stronger than he?" Will the sinner go measure arms with God? He is the Father Almighty, who can command legions. If we have no strength to resist him, it is irrational to disobey him.

2.) It is irrational because it is against all law and equity. We have our daily subsistence from God; in him we live and move. Is it not fitting that, as we live by him, we should live to him, that as God gives us our allowance, we should give him our allegiance?

2. It is a destructive sin. 2 Thessalonians 1:7–8 says, "The Lord Jesus shall be revealed from heaven with his mighty angels, in flaming fire, taking vengeance on them that obey not the gospel." Whoever refuses to obey God's will in commanding shall be sure to obey his will in punishing. The sinner, while thinking to slip the knot of obedience, twists the cord of his own damnation; he perishes without excuse, with no plea or apology to make for himself. Luke 12:47 says, "The servant which knew his lord's will, but did it not, shall be beaten with many stripes." God will say, why did you not obey? You knew how to do good but did not do it; therefore your blood is upon your own head.

Question: What means shall we use that we may obey?

Answer: First, serious consideration. Consider that God's commands are not burdensome: he commands nothing unreasonable (1 John 5:3). It is easier to obey the commands of God than to obey sin; sin's commands are the truly heavy ones. Let a man come under the power of any lust, and see how he wears himself out. What risks does he run, even endangering his health and his soul, to satisfy his lusts? What wearisome journeys did Antiochus Epiphanes make in persecuting the Jews! "They weary themselves to commit iniquity" (Jer 9:5); and are not God's commands easier to obey than that? Chrysostom says that virtue is easier than vice, and that temperance is less burdensome than drunkenness. Some have traveled to heaven with less effort than others spend traveling to hell.

Consider, second, that God commands nothing but what benefits us: "O Israel, what doth the Lord require of thee, but to fear the Lord thy God, and to keep his statutes, which I command thee this day, for thy good?" (Deut 10:12–13). To obey God is not so much our duty as our privilege; his commands carry their own reward within them. He bids us repent, and why? So that our sins may be blotted out (Acts 3:19). He commands us to believe, and why? So that we may be saved (Acts 16:31). There is love in every command, as if a king told one of his subjects to dig in a gold mine, and then gave him the gold for himself.

Answer 2: Second, earnest supplication. Ask for the help of the Spirit to carry us forward in obedience; God's Spirit makes obedience easy and delightful. If a magnet draws iron, the iron does not find it hard to move; if God's Spirit quickens and draws the heart, obedience is no longer hard. When a gale of the Spirit blows, we sail forward at full speed in obedience. Turn that promise into a prayer: "I will put my Spirit within you, and cause you to walk in my statutes" (Ezek 36:27). The promise encourages us, the Spirit enables us to obey.

Love

The rule of obedience being the moral law, comprehended in the Ten Commandments, the next question is,

Question 42: What is the sum of the Ten Commandments?

Answer: The sum of the Ten Commandments is, to love the Lord our God with all our heart, with all our soul, with all our strength, and with all our mind, and our neighbor as ourselves.

Deuteronomy 6:5 says, "Thou shalt love the Lord thy God, with all thy heart, and with all thy soul, and with all thy might." The duty called for is love, indeed, the full strength of love, "with all thy heart." God will lose none of our love. Love is the soul of religion, the very thing that rightly constitutes a Christian. Love is the queen of the graces; it shines and sparkles in God's eye, as the precious stones did on the breastplate of Aaron.

Question 1: What is love?

Answer: It is a holy fire kindled in the affections, by which a Christian is carried out strongly after God as the Supreme Good.

Question 2: What comes before love to God?

Answer: What comes before love is knowledge. The Spirit shines upon the understanding and reveals God's radiant beauties, his wisdom, holiness, mercy, and these entice and draw out love to God, like a lure to its object. As the old saying goes, no one desires what they do not know; those who do not know God cannot love him. If the sun has set in the understanding, there must be night in the affections.

Question 3: What does the essential nature of love consist in?

Answer: The nature of love lies in delighting in its object. As Aquinas put it, love is the lover's delight in the one loved. This is our loving God: taking delight in him, as Psalm 37:4 says, "Delight thyself also in the Lord," as a bride delights herself in her jewels. Grace changes a Christian's aims and delights.

Question 4: How must our love to God be qualified?

Answer 1: If it is a sincere love, we must love God with all our heart. The text says, "Thou shalt love the Lord thy God [Heb. Becol leuauca] with all thy heart." God will have the whole heart. We must not divide our love between God and sin. The true mother would not have her child divided, nor will God have the heart divided; it must be the whole heart.

Answer 2: We must love God for himself, for his own intrinsic excellencies; we must love him for his loveliness. As the saying goes, it is a harlot's love to love the dowry more than the husband. Hypocrites love God because he gives them corn and wine; we must love God for himself, for those shining perfections that are in him. Gold is loved for itself.

Answer 3: We must love God with all our might, in the Hebrew text, with our full vehemence. We must love God as much as we are able. Christians should be like seraphim burning in holy love; we can never love God as much as he deserves. Even the angels in heaven cannot love God as much as he deserves.

Answer 4: Love to God must be active within its own sphere. Love is an industrious affection: it sets the head studying for God, the hands working, the feet running in the ways of his commandments. It is called "the labour of love" (1 Thess 1:3). Mary Magdalene loved Christ, and poured her ointments on him. We think we never do enough for the one we love.

Answer 5: Love to God must be supreme above all else. God is the very essence of beauty, a whole paradise of delight, and he must hold first place in our love. Our love to God must rise above everything else, as oil floats above water; we must love God above possessions and relations. Love for family runs deep, there is a story in the French Academy of a daughter who, when her father was condemned to die by starvation, nursed him with her own breasts. But our love to God must be above father and mother (Matt 10:37). We may give the creature the milk of our love, but God must have the cream; the bride keeps the juice of her pomegranates for Christ (Song 8:2).

Answer 6: Our love to God must be constant, like the fire the Vestal virgins kept burning in Rome, which never went out. Love must be like the beating of the pulse, it continues as long as there is life (Song 8:7), "Many waters cannot quench love," not even the waters of persecution. As Ephesians 3:17 says, we must be "rooted in love." A branch withers if it does not grow from a root; for love not to die, it must be deeply rooted.

Question 5: What are the visible signs of our love to God?

Answer: First, if we love God, our desire is toward him. Scripture says, “The desire of our soul is to thy name” (Isa 26:8). He who loves God breathes after communion with him: “My soul thirsteth for the living God” (Ps 42:2). Those in love desire to be often conversing together; he who loves God desires to be much in his presence. He loves the ordinances, for they are the glass in which the glory of God shines. In the ordinances we meet with him whom our souls love; we have God's smiles and whispers, and foretastes of heaven. Those who have no desire for the ordinances have no love for God.

Answer: Second, the one who loves God cannot find contentment in anything without him. A hypocrite who pretends to love God can be content without God, so long as he has corn and wine; but a soul set on fire with love to God cannot be without him. Lovers faint away if they lose sight of the one they love. A gracious soul can want health, but cannot want God, who is “the health of his countenance” (Ps 43:5).

If God should say to a soul that loves him entirely, "Take your ease, swim in pleasure, indulge yourself in the delights of the world, but you shall not enjoy my presence," this would not satisfy the soul. And if God should say, "I will bring you up to heaven, but I will withdraw into an inner chamber, and you shall not see my face," this too would not satisfy the soul. It is a kind of hell to be without God. The philosopher says there can be no gold without the influence of the sun; there can be no golden joy in the soul without God's sweet presence and influence.

Answer: Third, the one who loves God hates whatever would separate him from God, and that is sin. Sin makes God hide his face; it is like an arsonist who destroys close friendships. This is why the keenest edge of a Christian's hatred is turned against sin: “I hate every false way” (Ps 119:128). True opposites can never be reconciled: one cannot love health and love poison too. So we cannot love God and love sin, which would destroy our communion with him.

Answer: Fourth, the sign is sympathy. Friends who love one another grieve over the evils that befall each other. Homer, describing Agamemnon's grief when he was forced to sacrifice his daughter, depicts all his friends weeping with him and accompanying him to the sacrifice in mourning. Lovers grieve together. If we have true love for God in our hearts, we cannot help grieving over what grieves him, we will take to heart the dishonors done to him, the excess, drunkenness, and contempt shown toward God and religion. “Rivers of waters run down mine eyes” (Ps 119:136), and so on. Some speak of the sins of others and laugh at them; surely such people have no love for God, since they can laugh at what grieves his Spirit. Does a son love his father if he can laugh to hear him mocked?

Answer: Fifth, the one who loves God labors to make him appear lovely to others. He does not merely admire God but speaks his praises, so that he might draw others into love for God as well. A woman in love will commend her lover; the love-sick bride in the Song of Songs extols Christ and delivers a eulogy of his worth, so that she might persuade others to love him too: “His head is as the most fine gold” (Song 5:11). True love for God cannot stay silent; it will speak eloquently of his renown. There is no better sign of loving God than making him appear lovely to others, and so winning converts to him.

Answer: Sixth, the one who loves God weeps bitterly at his absence. Mary comes weeping, "They have taken away the Lord" (John 20:2). One person cries, "My health is gone"; another, "My estate is gone." But the lover of God cries out, "My God is gone, I cannot enjoy the one whom I love!" What good are all the comforts of the world once God is absent? It is like a funeral banquet, full of food but empty of cheer: “I went mourning without the sun” (Job 30:28). If Rachel mourned so bitterly for the loss of her children, what image or words could capture the sorrow of a Christian who has lost God's sweet presence?

Such a soul pours out floods of tears, and in its lament seems to say to God, "Lord, you are in heaven, hearing the melodious songs and triumphs of angels, but I sit here in the valley of tears, weeping because you are gone. O when will you come to me and revive me with the light of your countenance!" Or else, "Lord, if you will not come to me, let me come to you, where I will have the perpetual smile of your face in heaven, and will never again have to complain, 'My beloved hath withdrawn himself.'"

Answer 7: The seventh visible sign: he who loves God is willing to do and suffer for him. He submits to God's commands, and he submits to God's will. First, he submits to God's commands: if God bids him mortify sin, love his enemies, be crucified to the world, he obeys. It is a vain thing for a man to say he loves God while he slights God's commands. Second, he submits to God's will: if God will have him suffer for him, he does not dispute, but obeys, as 1 Corinthians 13:7 says, love "endureth all things." Love made Christ suffer for us, and love will make us suffer for him. It is true that not every Christian is a martyr, but every Christian has a spirit of martyrdom in him: a disposition of mind to suffer, if God should call him to it, as 2 Timothy 4:6 says, "I am now ready to be offered up."

Not only were the sufferings ready for Paul, but Paul was ready for the sufferings. Origen chose rather to live despised in Alexandria than, like Plotinus, to deny the faith and be great in the prince's favor (Rev 12:11). Many say they love God but will not suffer the loss of anything for him. If Christ had said to us, "I love you well, you are dear to me, but I cannot suffer for you, I cannot lay down my life for you," we would have questioned his love very much. May not the Lord question ours, when we claim to love him but will endure nothing for his sake?
