John Wesley on Genesis 32:25

The angel prevailed not against him - That is, this discouragement did not shake his faith, nor silence his prayer. It was not in his own strength that he wrestled, nor by his own strength that he prevails; but by strength derived from heaven. That of Job illustrates this, Job 23:6. Will he plead against me with his great power? No; had the angel done so, Jacob had been crushed; but he would put strength in me: and by that strength Jacob had power over the angel, Hos 12:3. The angel put out Jacob's thigh, to shew him what he could do, and that it was God he was wrestling with, for no man could disjoint his thigh with a touch. Some think that Jacob felt little or no pain from this hurt; it is probable be did not, for he did not so much as halt 'till the struggle was over, Ge 32:31, and if so, that was an evidence of a divine touch indeed, which wounded and healed at the same time.
