Calvin for the win in 1 Peter 4:
"Yet Christ is not simply to be viewed as our example, when we speak of the mortificaion of the flesh; but it is by his Spirit that we are really made conformable to his death, so that it becomes effectual to the crucifying of our flesh. In short, as Peter at the end of the last chapter exhorted us to patience after the example of Christ, because death was to him a passage to life; so now from the same death he deduces a higher doctrine, that we ought to die to the flesh and to the world...He therefore says, arm yourselves, or be ye armed, intimating that we are really and effectually supplied with invincible weapons to subdue the flesh, if we partake as we ought of the efficacy of Christ’s death." - John Calvin, Commentary on the Catholic Epistles
