Q94. What does the LORD require in the first commandment?

A. That for the sake of my very salvation I avoid and flee all idolatry, witchcraft, superstition, and prayer to saints or to other creatures. Further, that I rightly come to know the only true God. trust in Him alone, submit to Him with all humility and patience, expect all good from Him only, and love, fear, and honour Him with all my heart. In short, that I forsake all creatures rather than do the least thing against His will.

1 Cor. 6:9-10
[9] Or do you not know that the unrighteous will not inherit the kingdom of God? Do not be deceived: neither the sexually immoral, nor idolaters, nor adulterers, nor men who practice homosexuality, [10] nor thieves, nor the greedy, nor drunkards, nor revilers, nor swindlers will inherit the kingdom of God.
1 Cor. 10:5-14
[5] Nevertheless, with most of them God was not pleased, for they were overthrown in the wilderness. [6] Now these things took place as examples for us, that we might not desire evil as they did. [7] Do not be idolaters as some of them were; as it is written, “The people sat down to eat and drink and rose up to play.” [8] We must not indulge in sexual immorality as some of them did, and twenty-three thousand fell in a single day. [9] We must not put Christ to the test, as some of them did and were destroyed by serpents, [10] nor grumble, as some of them did and were destroyed by the Destroyer. [11] Now these things happened to them as an example, but they were written down for our instruction, on whom the end of the ages has come. [12] Therefore let anyone who thinks that he stands take heed lest he fall. [13] No temptation has overtaken you that is not common to man. God is faithful, and he will not let you be tempted beyond your ability, but with the temptation he will also provide the way of escape, that you may be able to endure it. [14] Therefore, my beloved, flee from idolatry.

The Ten Commandments

Gratitude expressed through obedience to the Ten Commandments

Q86. Since we have been delivered from our misery by grace alone through Christ, without any merit of our own, why must we yet do good works?

A. Because Christ, having redeemed us by His blood, also renews us by His Holy Spirit to be His image, so that with our whole life we may show ourselves thankful to God for His benefits, and He may be praised by us. Further, that we ourselves may be assured of our faith by its fruits, and that by our godly walk of life we may win our neighbours for Christ.

Q87. Can those be saved who do not turn to God from their ungrateful and impenitent walk of life?

A. By no means. Scripture says that no unchaste person, idolater, adulterer, thief, greedy person, drunkard, slanderer, robber, or the like shall inherit the kingdom of God.

Q88. What is the true repentance or conversion of man?

A. It is the dying of the old nature and the coming to life of the new.

Q89. What is the dying of the old nature?

A. It is to grieve with heartfelt sorrow that we have offended God by our sin, and more and more to hate it and flee from it.

Q90. What is the coming to life of the new nature?

A. It is a heartfelt joy in God through Christ, and a love and delight to live according to the will of God in all good works.

Q91. But what are good works?

A. Only those which are done out of true faith, in accordance with the law of God, and to His glory, and not those based on our own opinion or on precepts of men.

Q92. What is the law of the LORD?

A. God spoke all these words, saying: I am the LORD your God, who brought you out of the land of Egypt, out of the house of bondage. 1. You shall have no other gods before Me. 2. You shall not make for yourself a graven image, 2. or any likeness of anything that is in heaven above, 2. or that is in the earth beneath, 2. or that is in the water under the earth; 2. you shall not bow down to them or serve them; 2. for I the LORD your God am a jealous God, 2. visiting the iniquity of the fathers upon the children 2. to the third and fourth generation 2. of those who hate Me, 2. but showing steadfast love to thousands of those 2. who love Me and keep My commandments. 3. You shall not take the Name of the LORD your God 3. in vain; 3. for the LORD will not hold him guiltless 3. who takes His Name in vain. 4. Remember the sabbath day, to keep it holy. 4. Six days you shall labour, and do all your work; 4. but the seventh day is a sabbath to the LORD your 4. God; 4. in it you shall not do any work, 4. you, or your son, or your daughter, 4. your manservant, or your maidservant, 4. or your cattle, 4. or the sojourner who is within your gates; 4. for in six days the LORD made heaven and earth, 4. the sea, and all that is in them, 4. and rested the seventh day; 4. therefore the LORD blessed the sabbath day 4. and hallowed it. 5. Honour your father and your mother, 5. that your days may be long 5. in the land which the LORD your God gives you. 6. You shall not kill. 7. You shall not commit adultery. 8. You shall not steal. 9. You shall not bear false witness against your neighbour. 10. you shall not covet your neighbour's house; 10. you shall not covet your neighbour's wife, 10. or his manservant, or his maidservant, 10. or his ox, or his ass, 10. or anything that is your neighbour's.

Q93. How are these commandments divided?

A. Into two parts. The first teaches us how to live in relation to God; the second, what duties we owe our neighbour.

Q94. What does the LORD require in the first commandment?

A. That for the sake of my very salvation I avoid and flee all idolatry, witchcraft, superstition, and prayer to saints or to other creatures. Further, that I rightly come to know the only true God. trust in Him alone, submit to Him with all humility and patience, expect all good from Him only, and love, fear, and honour Him with all my heart. In short, that I forsake all creatures rather than do the least thing against His will.

Q95. What is idolatry?

A. Idolatry is having or inventing something in which to put our trust instead of, or in addition to, the only true God who has revealed Himself in His Word.

Q96. What does God require in the second commandment?

A. We are not to make an image of God in any way, nor to worship Him in any other manner than He has commanded in His Word.

Q97. May we then not make any image at all?

A. God cannot and may not be visibly portrayed in any way. Creatures may be portrayed, but God forbids us to make or have any images of them in order to worship them or to serve God through them.

Q98. But may images not be tolerated in the churches as "books for the laity"?

A. No, for we should not be wiser than God. He wants His people to be taught not by means of dumb images but by the living preaching of His Word.

Q99. What is required in the third commandment?

A. We are not to blaspheme or to abuse the Name of God by cursing, perjury, or unnecessary oaths, nor to share in such horrible sins by being silent bystanders. In short, we must use the holy Name of God only with fear and reverence, so that we may rightly confess Him, call upon Him, and praise Him in all our words and works.

Q100. Is the blaspheming of God's Name by swearing and cursing such a grievous sin that God is angry also with those who do not prevent and forbid it as much as they can?

A. Certainly, for no sin is greater or provokes God's wrath more than the blaspheming of His Name. That is why He commanded it to be punished with death.

Q101. But may we swear an oath by the Name of God in a godly manner?

A. Yes, when the government demands it of its subjects, or when necessity requires it, in order to maintain and promote fidelity and truth, to God's glory and for our neighbour's good. Such oath-taking is based on God's Word and was therefore rightly used by saints in the Old and the New Testament.

Q102. May we also swear by saints or other creatures?

A. No. A lawful oath is a calling upon God, who alone knows the heart, to bear witness to the truth, and to punish me if I swear falsely. No creature is worthy of such honour.

Q103. What does God require in the fourth commandment?

A. First, that the ministry of the gospel and the schools be maintained and that, especially on the day of rest, I diligently attend the church of God to hear God's Word, to use the sacraments, to call publicly upon the LORD, and to give Christian offerings for the poor. Second, that all the days of my life I rest from my evil works, let the LORD work in me through His Holy Spirit, and so begin in this life the eternal sabbath.

Q104. What does God require in the fifth commandment?

A. That I show all honour, love, and faithfulness to my father and mother and to all those in authority over me, submit myself with due obedience to their good instruction and discipline, and also have patience with their weaknesses and shortcomings, since it is God's will to govern us by their hand.

Q105. What does God require in the sixth commandment?

A. I am not to dishonour, hate, injure, or kill my neighbour by thoughts, words, or gestures, and much less by deeds, whether personally or through another; rather, I am to put away all desire of revenge. Moreover, I am not to harm or recklessly endanger myself. Therefore, also, the government bears the sword to prevent murder.

Q106. But does this commandment speak only of killing?

A. By forbidding murder God teaches us that He hates the root of murder, such as envy, hatred, anger, and desire of revenge, and that He regards all these as murder.

Q107. Is it enough, then, that we do not kill our neighbour in any such way?

A. No. When God condemns envy, hatred, and anger, He commands us to love our neighbour as ourselves, to show patience, peace, gentleness, mercy, and friendliness toward him, to protect him from harm as much as we can, and to do good even to our enemies.

Q108. What does the seventh commandment teach us?

A. That all unchastity is cursed by God. We must therefore detest it from the heart and live chaste and disciplined lives, both within and outside of holy marriage.

Q109. Does God in this commandment forbid nothing more than adultery and similar shameful sins?

A. Since we, body and soul, are temples of the Holy Spirit, it is God's will that we keep ourselves pure and holy. Therefore He forbids all unchaste acts, gestures, words, thoughts, desires, and whatever may entice us to unchastity.

Q110. What does God forbid in the eighth commandment?

A. God forbids not only outright theft and robbery but also such wicked schemes and devices as false weights and measures, deceptive merchandising, counterfeit money, and usury; we must not defraud our neighbour in any way, whether by force or by show of right. In addition God forbids all greed and all abuse or squandering of His gifts.

Q111. What does God require of you in this commandment?

A. I must promote my neighbour's good wherever I can and may, deal with him as I would like others to deal with me, and work faithfully so that I may be able to give to those in need.

Q112. What is required in the ninth commandment?

A. I must not give false testimony against anyone, twist no one's words, not gossip or slander, nor condemn or join in condemning anyone rashly and unheard. Rather, I must avoid all lying and deceit as the devil's own works, under penalty of God's heavy wrath. In court and everywhere else, I must love the truth, speak and confess it honestly, and do what I can to defend and promote my neighbour's honour and reputation.

Q113. What does the tenth commandment require of us?

A. That not even the slightest thought or desire contrary to any of God's commandments should ever arise in our heart. Rather, we should always hate all sin with all our heart, and delight in all righteousness.

Q114. But can those converted to God keep these commandments perfectly?

A. No. In this life even the holiest have only a small beginning of this obedience. Nevertheless, with earnest purpose they do begin to live not only according to some but to all the commandments of God.

Q115. If in this life no one can keep the ten commandments perfectly, why does God have them preached so strictly?

A. First, that throughout our life we may more and more become aware of our sinful nature, and therefore seek more eagerly the forgiveness of sins and righteousness in Christ. Second, that we may be zealous for good deeds and constantly pray to God for the grace of the Holy Spirit, that He may more and more renew us after God's image, until after this life we reach the goal of perfection.
