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.

As—marking their present actual character as "born again" (1Pe 1:3, 22).

Contrast Eph 5:6, "the children of disobedience." Compare 1Pe 1:17, "obeying the Father" whose "children" ye are. Having the obedience of faith (compare 1Pe 1:22) and so of practice (compare 1Pe 1:16, 18). "Faith is the highest obedience, because discharged to the highest command" [Luther].

the former lusts in—which were characteristic of your state of ignorance of God: true of both Jews and Gentiles. The sanctification is first described negatively (1Pe 1:14, "not fashioning yourselves," &c.; the putting off the old man, even in the outward fashion, as well as in the inward conformation), then positively (1Pe 1:15, putting on the new man, compare Eph 4:22, 24). "Lusts" flow from the original birth-sin (inherited from our first parents, who by self-willed desire brought sin into the world), the lust which, ever since man has been alienated from God, seeks to fill up with earthly things the emptiness of his being; the manifold forms which the mother-lust assumes are called in the plural lusts. In the regenerate, as far as the new man is concerned, which constitutes his truest self, "sin" no longer exists; but in the flesh or old man it does. Hence arises the conflict, uninterruptedly maintained through life, wherein the new man in the main prevails, and at last completely. But the natural man knows only the combat of his lusts with one another, or with the law, without power to conquer them.
