Good point.
The power of Christ rested on Paul by means of that thorn in his flesh, the messenger of Satan to buffet him. Paul gloried in his infirmities that the power of Christ could rest upon him. God did not grant Paul’s prayer for this thorn to depart from him (2 Corinthians 12:7-10).
In this instance suffering in the flesh rendered great spiritual benefits. But one of the greatest benefits is the ceasing from sin in the believer.
1 Peter 4:1
Forasmuch then as Christ hath suffered for us in the flesh, arm yourselves likewise with the same mind: for he that hath suffered in the flesh hath ceased from sin
Well said. Did you know that "thorn in the flesh" in this passage is actually a Hebrew idiom and is not literally an ailment in our body, but
people opposed to us causing us trouble? "Messengers of Satan." This passage has nothing to do with Paul's actual ailments, like his poor eyesight.
Judges 2:
Then the Angel of the Lord came up from Gilgal to Bochim, and said: “I led you up from Egypt and brought you to the land of which I swore to your fathers; and I said, ‘I will never break My covenant with you. 2 And you shall make no covenant with the inhabitants of this land; you shall tear down their altars.’ But you have not obeyed My voice. Why have you done this? 3 Therefore I also said, ‘I will not drive them out before you; but they shall be
thorns in your side, and their gods shall be a snare to you.’ ” 4 So it was, when the Angel of the Lord spoke these words to all the children of Israel, that the people lifted up their voices and wept.
