Sometimes as a gift, as St. Peter has already exhibited it in the third chapter; and to those first, who are built up and instructed in the faith that we are ransomed, and our sins taken away by the blood of Christ; and so he is a gift and bestowment upon us, which none can receive except by faith. Whereof he speaks where he says, "Christ has once suffered for our sins." That is certainly the grand doctrine, and the most precious one of the Gospel. Again, Christ is set before us and offered to us as an example and pattern for us to follow. For if we only receive Christ, through faith, as a free gift, we shall go farther and do ourselves as He has done for us, and imitate Him in His whole life and sufferings. In this manner St. Peter presents it here. But he does not speak here particularly of those marks of the love which leads us to befriend our neighbor, and do good, which are called, specifically, good works (for he had said enough of this above), but of such evidences as concern our personal experience, and are of service in strengthening our faith, that sin may be put to death in the flesh, and we thereby become of so much better service to our neighbor. For if I control my body so that it be not lustful, then can I leave my neighbor, his wife or child, at peace; while if I subdue hate and envy, I shall become so much better prepared to be kind and friendly toward my neighbor. We have repeated often enough already that we are justified through faith, and thus have the Lord Christ as ours; still we must also do good works and show kindness to our neighbor. For we are never entirely purified while we live on earth, and every one still finds in his body evil lusts. The believer indeed prays for the death of sin and the gift of heaven, but is not yet become entirely and completely strong; but as Christ described the Samaritan, who was not yet healed, but was laid under restrictions and directions that he might become sound, so it is also with us. If we believe, then is our sin restrained,--that is, the disease which we have derived from Adam, and we begin to recover. But it is the case, in one more, in another less, that in proportion as one mortifies and subdues the flesh, so much does his faith increase. So that if we have these two things, faith and love, our future experience will be, that we shall continue to drive sin before us till we die. Therefore St. Peter says, _arm yourselves with the same mind_; that is, take up a firm purpose, and strengthen yourselves with the mind which you receive from Christ; for, if we are Christians, then must we also say, My Master has suffered and spilt His blood for me, and has died for my sake. Should I then be so base as not to love Him? While the Master runs upon the spears' points in the conflict, how much more should the servant advance with joy? Thus do we awaken a courage such that we press onward, and arm ourselves in our own minds so as joyfully to persevere.
