1. This epistle selection, too, is an admonition to good works, or the fruits of faith. It touches upon nearly every condition of life, teaching how each individual should live and conduct himself. But first, Peter admonishes Christians in general that in their intercourse with gentiles, or the unbelieving world, they give no real occasion for censure or reproach concerning their conduct. The admonition seems to hinge upon the fact that Christians, as the apostle reminds them in the first and second chapters, have been called to a lively, a never-dying, hope of an imperishable inheritance in heaven, and of eternal joy and salvation; that they are now redeemed, having obtained remission of sins through the precious blood of Christ; and again, that they are become a holy nation and royal priesthood, to show forth and magnify the grace of God, they who in time past were not God's people and had not obtained grace. "But now," Peter would say, "you have obtained grace through the divine calling of Christ, through the suffering of your Lord. Live, then, as a holy people of God and citizens of heaven."
2. We have already heard that in the Christian life are two essential principles, two principles upon which Christian teachers may lay emphasis. First, faith in the fact that through Christ's blood we are released from sin and have forgiveness; second, being forgiven, our natures are to be changed and we are to walk in newness of life. In baptism, when we first believe, we obtain not only remission of sins whereby we are of grace made children of God, but also the power to purge out, to mortify, the remaining sins. Our transgressions are not forgiven, Paul says (Rom 1, 6), with the privilege of continuing in them, as the insolent rejecters of grace imagine. It is this way: Our sins being blotted out through the blood of Christ, we need not to make remuneration or render satisfaction for them; we are children of grace and enjoy forgiveness. Nevertheless, inherent sin is not entirely purged out, or mortified.
