For though he was crucified through weakness, yet he lives by the power of God. For we also are weak in him, but we shall live with him by the power of God toward you.
All Commentaries on 2 Corinthians 13:4 Go To 2 Corinthians 13
This is a difficult passage which causes problems for many people. What is meant here by “weakness”? In Scripture weakness can refer to bodily illness, and it can also mean not being securely grounded in faith. But there is a third possibility, and that is what we find here. Weakness can mean persecutions, trials, plottings and the like. Christ was not weak in body or in spirit, but he was persecuted and put to death. It was not because of any inherent weakness that he went to the cross; on the contrary, he chose to die in that way in order to give us life in the power of God.
