1. Jacob received no blessing as long as he was struggling (Gen 32:25). Jacob was resisting the man who came to him, instead of submitting. Trusting in the Lord is the condition to be in to receive blessing, not striving against Him.
2. Jacob's humiliation is the beginning of blessing (Gen 32:25). The angel touched the hollow of Jacob's thigh. His strength was gone, as his thigh is out of joint. The thigh out of joint humbled Jacob, and led him to see his weakness, and that brought him in joint with God.
3. Jacob's clinging is the secret of his blessing (Gen 32:26). Jacob will not let the angel go till he blesses him; but mark, it is while he clings he is blessed, and not while he is striving. The resistance of unbelief and self-will will never receive blessing, but the tenacity of faith always does.
4. Jacob's changed name an evidence of blessing (Gen 32:28). From Jacob, a supplanter, he is called "Israel," i.e., a prince with God. In like manner they who believe in Christ have their name changed from children of wrath (Eph 2:3) to children of God (Jhn 1:12); from sinners to saints.
