1. This text, too, is an admonition to Christian living, a discourse concerning the fruits of a good tree, a figure applied to the Christian; in other words, concerning the fruits of the one who, through faith, has obtained redemption from sin and death and has a place in the kingdom of grace and of eternal life. Such a one is exhorted to live henceforth in a manner indicative of the fact that he has apprehended the treasure of salvation and is become a new man. EXHORTATION TO SOBERNESS. 2. Certain good works are also introduced, and in the first part of our text Peter makes an especially emphatic continuation of the admonition in the foregoing part of the chapter, warning Christians to abstain from gross vices--carnal lusts--which in the world lead to obscenity, and from the wild, disorderly, swinish lives of the heathen world, lives of gormandizing, guzzling and drunkenness. Peter admonishes Christians to endeavor to be "sober unto prayer." The epistle was written chiefly to the Greeks, the masses of which people were very social, and inclined to carouse and gormandize. And we Germans are accused of the same excess; not without some reason either. 3. With intent to turn Christians from these vices unto temperance and sobriety, Peter reminds them, as all the apostles are wont to do, of the obligations particularly incident to the Christian calling, to the only true, divine service, the things for the sake of which they have become Christians and which distinguish them from the remainder of the world. His meaning is: It is not for Christians to lead lives heathenish, profligate and riotous; to indulge in gormandizing, guzzling, carousing and demoralizing of themselves. They have something nobler to do. First, in that they are to become different beings, and be occupied with the Word of God wherefrom they derive their new birth and whereby they preserve it. Second, being born anew, they have enemies to fight; so long as they live on earth, they must combat the devil, also their own flesh, which is corrupted by the devil until it is full of evil lusts. Having, then, to assume the obligations of this calling and contest, they must not give way to drowsy indolence; much less may they become foolish, drunken sots, indifferent to all issues and heedless of their obligations. Rather, they have need to be watchful and sober, ever ready with the Word of God and with prayer.
