Commentaries
1:13-16 As the traveller, the racer, the warrior, and the labourer, gathered in their long and loose garments, that they might be ready in their business, so let Christians do by their minds and affections. Be sober, be watchful against all spiritual dangers and enemies, and be temperate in all behaviour. Be sober-minded in opinion, as well as in practice, and humble in your judgment of yourselves. A strong and perfect trust in the grace of God, is agreeable with best endeavours in our duty. Holiness is the desire and duty of every Christian. It must be in all affairs, in every condition, and towards all people. We must especially watch and pray against the sins to which we are inclined. The written word of God is the surest rule of a Christian's life, and by this rule we are commanded to be holy every way. God makes those holy whom he saves.
15. Literally, "But (rather) after the pattern of Him who hath called you (whose characteristic is that He is) holy, be (Greek, 'become') ye yourselves also holy." God is our grand model. God's calling is a frequently urged motive in Peter's Epistles. Every one that begets, begets an offspring resembling himself [Epiphanius]. "Let the acts of the offspring indicate similarity to the Father" [Augustine].
conversation—deportment, course of life: one's way of going about, as distinguished from one's internal nature, to which it must outwardly correspond. Christians are already holy unto God by consecration; they must be so also in their outward walk and behavior in all respects. The outward must correspond to the inward man.
