2 Corinthians 13:4

For he was crucified through weakness, yet he liveth through the power of God. For we also are weak in him, but we shall live in him through the power of God toward you.

Macknight's paraphrase of 2 Corinthians 13:4 is thus:

For, though indeed Christ was crucified by reason of the weakness of his human nature, which was liable to death, yet he now liveth by the power of God. And though I also, his apostle, am weak, as he was, being subject to persecution, infamy, death; I shall nevertheless show myself alive in him, by exercising the power of God among you, punishing you severely if you do not repent.[13]

The weakness of Christ mentioned here applies only to those weaknesses inherent in the fact of incarnation. Being a man, Christ was subject to death. "The Lord assumed our nature with all its infirmities, death included, bore them all for our sake, and then shook them all off forever when he rose from the dead."[14]

We shall live in him through the power of God in you ... By this, Paul meant that severe punishment would be visited upon gross and impenitent sinners at Corinth. Just as Christ the humble sufferer has now ascended to the throne of God, Paul will put aside the weakness of his patience and forbearance and exercise the full power of his apostolic office against the wicked deceivers. Some believe that Paul referred to supernatural judgments like that which afflicted Elymas.
