Therefore, since Christ suffered in his body, arm yourselves also with the same attitude, because whoever suffers in the body is done with sin. As a result, they do not live the rest of their earthly lives for evil human desires, but rather for the will of God. For you have spent enough time in the past doing what pagans choose to do—living in debauchery, lust, drunkenness, orgies, carousing and detestable idolatry. They are surprised that you do not join them in their reckless, wild living, and they heap abuse on you. But they will have to give account to him who is ready to judge the living and the dead. For this is the reason the gospel was preached even to those who are now dead, so that they might be judged according to human standards in regard to the body, but live according to God in regard to the spirit.
The end of all things is near. Therefore be alert and of sober mind so that you may pray. Above all, love each other deeply, because love covers over a multitude of sins. Offer hospitality to one another without grumbling. Each of you should use whatever gift you have received to serve others, as faithful stewards of God’s grace in its various forms. If anyone speaks, they should do so as one who speaks the very words of God. If anyone serves, they should do so with the strength God provides, so that in all things God may be praised through Jesus Christ. To him be the glory and the power for ever and ever. Amen.
Peter wrote to Christians who had once lived what scripture calls fleshly, sinful lives. The list he gives is obvious, and today is no different. Pornography for example is a huge market, and many it has taken down. Of course there are other sins maybe more acceptable to society at large, but nevertheless destructive as well. Usually especially to relationships, and also simply to one’s well being.
Peter’s words alluding to Christ’s suffering, and then saying we should arm ourselves with the same, in a kind of bodily way, so it impacts how we live seems I suppose Catholic to many of us. So be it. Peter points back to their wild, reckless past as an incentive to live differently in the present. And in the face of ridicule for doing so. In so doing, they will be following Christ, living out that following. And to do so, Peter is suggesting, again, that they’re to arm themselves with a mindset which embraces suffering in the body. Actually what might be spoken of here is the refusal to do what one is tempted to do in the body. We realize that the rest of the letter speaks of suffering in terms of persecution for their faith.
This incentive to live godly lives because of past ungodliness might be especially helpful to younger Christians. But it should provide incentive to us all. It actually puts us in a sphere of life and experience where we live bodily for something else entirely. Not to indulge ourselves, but to deny ourselves. Not really to deny our humanity, either. The New International Version adds “evil” to “human desires” to make that clear (click link above to compare with Greek, and other translations). But in doing so, it maybe to some extent loses a certain sense of what this scripture is saying. Yes, strictly speaking Peter is not telling those Christians that they can’t eat and drink and marry, etc. But what the passage does seem to be saying is that a Christian should live not for the fulfillment of legitimate human desires, but rather for the will of God. That such an attitude is a necessary fortification to not drift into what actually is evil. And important even, in us fulfilling God’s will in our lives.
I include what is the second paragraph in the translation above, because Peter puts that together with the call to live differently. It is to be done so in Christian love with acts of service.
Our lives are lived bodily. What we do and don’t do are important. We live bent on doing God’s will. When we fail, of course there’s always confession and repentance, and if need be for a serious enough offense, restoration. This passage indeed points to reformation, to a changed life, completely different than the world not only accepts, but often celebrates. We seek to follow Christ in a different way. Finding our fulfillment, including as humans, in that. In and through Jesus.
