Have the Mind of Christ

Chapter four opens with a military verb and a decisive turn. Because Christ suffered in the flesh, Peter says, arm yourselves with His way of thinking. The Christian life is not a leisure; it is an enlistment. The mind we are to put on is the mind of the suffering Servant, the One who chose the Father's will over the approval of the crowd. And once that mind is on, the shape of the rest of our days is set: no longer for human passions, but for the will of God. This passage draws a clean line under the old life, names the social cost of the new life, and steadies us with the coming judgment and the certain life of God.

1. Arm yourselves with His thinking

The command: "Since therefore Christ suffered in the flesh, arm yourselves with the same way of thinking" (4:1). The verb "arm" (hoplisasthai) is the word for taking up weapons. Peter treats the mind of Christ as a soldier's equipment, something you deliberately put on for the campaign. And the "same way of thinking" (ennoian) is the resolve that chose obedience through suffering rather than sin through escape. Christ decided to do the Father's will whatever it cost in the flesh. That same decision is now to govern our minds.

Then a striking phrase: "for whoever has suffered in the flesh has ceased from sin" (4:1). The meaning is debated, and there are two faithful readings. The first: suffering for righteousness breaks the power of sin in a believer's life, because the trial that is borne in obedience teaches the soul that sin's pleasures are not worth compromise. The second, and more common among evangelicals: the believer who has, in union with Christ, "suffered in the flesh" (died to the old self at conversion, cf. Rom 6) has broken with sin as a ruling power. David Guzik collects both and leans to the second: the one identified with Christ's suffering has "made a clean break with sin" (Guzik on 1 Pet 4:1). Either way, the point is devotional: the cross-mind severs the grip of sin.

2. The rest of the time, for God's will

The purpose clause: "so as to live for the rest of the time in the flesh no longer for human passions but for the will of God" (4:2). Notice the framing of the whole remaining life: the rest of the time in the flesh. Peter sees the believer's present life as a defined, bounded season, the last stretch before glory, and the question is what it is for. Not for human passions. For the will of God. Two options, two masters, no third category. The armed mind lives the remainder for God.

Then Peter draws the line under the past with a wry sadness: "For the time that is past suffices for doing what the Gentiles want to do" (4:3). The old life is enough. There has been more than enough of it. He lists six marks of it: sensuality, passions, drunkenness, orgies, drinking parties, lawless idolatry. The list is not theoretical; it is the world these Gentile believers had come out of. Peter's point is not to scold but to close the account: that chapter is finished. The royal priest does not return to the flood he was rescued from.

3. The surprise of the watching world

Now the social cost, named honestly: "With respect to this they are surprised when you do not join them in the same flood of debauchery, and they malign you" (4:4). The old companions are surprised. They expected you to come back to the flood. When you do not, the surprise curdles into slander. This is the same dynamic of 2:12 and 3:16, but here Peter names the source: the world does not understand the new life, and misunderstanding breeds resentment. The believer who arms with Christ's mind should expect to be misunderstood by the people who still live in the mind of the world.

4. The Judge who is ready, and the dead who live

So Peter steadies us with the coming judgment: "but they will give account to him who is ready to judge the living and the dead" (4:5). The slanderer is not the final audience. There is a Judge, already ready, before whom both the living and the dead will give account. The believer can afford to be maligned now, because the account will be settled then. This is the same comfort Christ modelled in 2:23, entrusting to the One who judges justly.

Then verse 6, the second hard saying of the chapter: "For this is why the gospel was preached even to those who are dead, that though judged in the flesh the way people are, they might live in the spirit the way God does." Two main evangelical readings are held. The first (and most common): the gospel was preached (past tense) to believers who have now died, so that though they are judged in the flesh (they died like all people die), they live in the spirit (they are alive with God). This fits Peter's comfort to a church whose members were being taken by persecution. The second (a smaller number): it refers to those who heard the gospel in the era of 3:19. The first reading is far better supported by the context and is the plain sense: Peter is reassuring the living that their dead brethren, who heard and believed the gospel, are alive with God though they died in the flesh (Henry on 1 Pet 4:6; cf. Guzik on 1 Pet 4:6). The encouragement: death in the flesh is not the end of life in the spirit.

Application — head, heart, hands

Head. Believe that the mind of Christ is given to you as armour, that it severs the grip of sin, and that the rest of your days are to be lived for the will of God. The slander of the watching world is not the final verdict; the ready Judge is.

Heart. Cultivate the resolve of Gethsemane, the will to obey whatever the cost. Mortify the nostalgia for the old flood and the fear of the world's misunderstanding. The chapter of the past is finished.

Hands. Arm yourself this week with one specific "same way of thinking" decision. Refuse one passion, choose one act of the Father's will, and accept the social cost if it comes. The royal priest lives the remainder under orders.
