2 Corinthians 4:10

bearing about in the body the dying of the Lord Jesus--that is, having my body exposed to being put to death in the cause of Jesus (the oldest manuscripts omit "the Lord"), and having in it the marks of such sufferings, I thus bear about wheresoever I go, an image of the suffering Saviour in my own person (Co2 4:11; Co2 1:5; compare Co1 15:31). Doubtless, Paul was exposed to more dangers than are recorded in Acts (compare Co2 7:5; Co2 11:26). The Greek for "the dying" is literally, "the being made a corpse," such Paul regarded his body, yet a corpse which shares in the life-giving power of Christ's resurrection, as it has shared in His dying and death. that the life also of Jesus might be made manifest in our body--rather, "may be." The name "Jesus," by itself is often repeated here as Paul seems, amidst sufferings, peculiarly to have felt its sweetness. In Co2 4:11 the same words occur with the variation, "in our mortal flesh. The fact of a dying, corpse-like body being sustained amidst such trials, manifests that "the (resurrection) life also," as well as the dying, "of Jesus," exerts its power in us. I thus bear about in my own person an image of the risen and living, as well as of the suffering, Saviour. The "our" is added here to "body," though not in the beginning of the verse. "For the body is ours not so much in death, as in life" [BENGEL].
