The Ten Commandments Part 2c
By Martin Luther

Thou shalt not take the name of the LORD thy God in vain
Exodus 20:7

Therefore I advise and exhort as before that by means of warning and threatening, restraint and punishment, the children be trained betimes to shun falsehood, and especially to avoid the use of God's name in its support.( Proverbs 22:15; Proverbs 23:13; Proverbs 29:15;) For where they are allowed to do as they please, no good will result, as is even now evident that the world is worse than it has ever been and that there is no government, no obedience, no fidelity, no faith, but only daring, unbridled men, whom no teaching or reproof helps; all of which is God's wrath and punishment for such wanton contempt of this commandment.

On the other hand, they should be constantly urged and incited to honor God's name, and to have it always upon their lips in everything that may happen to them or come to their notice: For that is the true honor of His Name, to look to it and implore it for all consolation, so that (as we have heard above) first the heart by faith gives God the honor due Him, and afterwards the lips by confession. (Proverbs 22:6; Romans 10:8-9; Isaiah 45:23;)

This is also a blessed and useful habit and very effectual against the devil, who is ever about us, and lies in wait to bring us into sin and shame, calamity and trouble,(1 Peter 5:8;) but who is very loath to hear God's name, and cannot remain long where it is uttered and called upon from the heart. And, indeed, many a terrible and shocking calamity would befall us if, by our calling upon His name, God did not preserve us. I have myself tried it, and learned by experience that often sudden great calamity was immediately averted and removed during such invocation. To vex the devil, I say, we should always have this holy name in our mouth, so that he may not be able to injure us as he wishes.(Zechariah 3:8; Jude 1:9; Mark 8:33; Luke 4:8; Mark 1:34;)

For this end it is also of service that we form the habit of daily commending ourselves to God, with soul and body, wife, children, servants, and all that we have, against every need that may occur; whence also the blessing and thanksgiving at meals, and other prayers, morning and evening, have originated and remain in use. This would be more pleasing and acceptable to God than all false sanctity. (Psalm 9:10; Isaiah 26:9; Psalm 27:8; Proverbs 7:15; Mark 1:37;)

Behold, thus we might train our youth in a childlike way and playfully in the fear and honor of God, so that the First and Second Commandments might be well observed and in constant practice. Then some good might take root, spring up and bear fruit, and men grow up whom an entire land might relish and enjoy. Moreover, this would be the true way to bring Up children well as long as they can become trained with kindness and delight. For what must be enforced with rods and blows only will not develop into a good breed and at best they will remain godly under such treatment no longer than while the rod is upon their back.

But this [manner of training] so spreads its roots in the heart that they fear God more than rods and clubs. This I say with such simplicity for the sake of the young, that it may penetrate their minds. For since we are preaching to children, we must also prattle with them. Thus we have prevented the abuse and have taught the right use of the divine name, which should consist not only in words, but also in practices and life, so that we may know that God is well pleased with this and will as richly reward it as He will terribly punish the abuse.
