[Sidenote: The Second Commandment]
The second work, next to faith, is the work of the Second Commandment, that we shall honor God's Name and not take it in vain. This, like all the other works, cannot be done without faith; and if it is done without faith, it is all sham and show. After faith we can do no greater work than to praise, preach, sing and in every way exalt and magnify God's glory, honor and Name.
And although I have said above,[16] and it is true, that there is no difference in works where faith is and does the work, yet this is true only when they are compared with faith and its works. Measured by one another there is a difference, and one is higher than the other. Just as in the body the members do not differ when compared with health, and health works in the one as much as in the other; yet the works of the members are different, and one is higher, nobler, more useful than the other [Rom. 12:4, 1 Cor. 12]; so, here also, to praise God's glory and Name is better than the works of the other Commandments which follow; and yet it must be done in the same faith as all the others.
But I know well that this work is lightly esteemed, and has indeed become unknown. Therefore we must examine it further, and will say no more about the necessity of doing it in the faith and confidence that it pleases God. Indeed there is no work in which confidence and faith are so much experienced and felt as in honoring God's Name; and it greatly helps to strengthen and increase faith, although all works also help to do this, as St. Peter says, II. Peter i: "Wherefore the rather, brethren, give diligence through good works to make your calling and election sure."

XIX. The First Commandment forbids us to have other gods, and thereby commands that we have a God, the true God, by a firm faith, trust, confidence, hope and love, which are the only works whereby a man can have, honor and keep a God; for by no other work can one find or lose God except by faith or unbelief, by trusting or doubting; of the other works none reaches quite to God. So also in the Second Commandment we are forbidden to use His Name in vain. Yet this is not to be enough, but we are thereby also commanded to honor, call upon, glorify, preach and praise His Name. And indeed it is impossible that God's Name should not be dishonored where it is not rightly honored. For although it be honored with the lips, bending of the knees, kissing and other postures, if this is not done in the heart by faith, in confident trust in God's grace, it is nothing else than an evidence and badge of hypocrisy.
See now, how many kinds of good works a man can do under this Commandment at all times and never be without the good works of this Commandment, if he will; so that he truly need not make a long pilgrimage or seek holy places. For, tell me, what moment can pass in which we do not without ceasing receive God's blessings, or, on the other hand, suffer adversity? But what else are God's blessings and adversities than a constant urging and stirring up to praise, honor, and bless God, and to call upon His Name? Now if you had nothing else at all to do, would you not have enough to do with this Commandment alone, that you without ceasing bless, sing, praise and honor God's Name? And for what other purpose have tongue, voice, language and mouth been created? As Psalm li. says: "Lord, open Thou my lips, and my mouth shall show forth Thy praise." [Ps. 51:15] Again: "My tongue shall sing aloud of Thy mercy." [Ps. 51:14]
What work is there in heaven except that of this Second Commandment? As it is written in Psalm lxxxiv: "Blessed are they that dwell in Thy house: they will be for ever praising Thee." [Ps. 84:4] So also David says in Psalm xxxiv: "God's praise shall be continually in my mouth." [Ps. 34:1] And St. Paul, I. Corinthians x: "Whether therefore ye eat or drink, or whatsoever ye do, do all to the glory of God." [1 Cor. 10:31] Also Colossians iii: "Whatsoever ye do in word or deed, do all in the Name of the Lord Jesus, giving thanks to God and the Father." [Col. 3:17] If we were to observe this work, we would have a heaven here on earth and always have enough to do, as have the saints in heaven.

XX. On this is based the wonderful and righteous judgment of God, that at times a poor man, in whom no one can see many great works, in the privacy of his home joyfully praises God when he fares well, or with entire confidence calls upon Him when he fares ill, and thereby does a greater and more acceptable work than another, who fasts much, prays much, endows churches, makes pilgrimages, and burdens himself with great deeds in this place and in that. Such a fool opens wide his mouth, looks for great works to do, and is so blinded that he does not at all notice this greatest work, and praising God is in his eyes a very small matter compared with the great idea he has formed of the works of his own devising, in which he perhaps praises himself more than God, or takes more pleasure in them than he does in God; and thus with his good works he storms against the Second Commandment and its works. Of all this we have an illustration in the case of the Pharisee and the Publican in the Gospel. [Luke 18:10 f.] For the sinner calls upon God in his sins, and praises Him, and so has hit upon the two highest Commandments, faith and God's honor. The hypocrite misses both and struts about with other good works by which he praises himself and not God, and puts his trust in himself more than in God. Therefore he is justly rejected and the other chosen.
