Ge 32:24 ¶ Then Jacob was left alone, and a man wrestled with him until daybreak.
Ge 32:25 And when he saw that he had not prevailed against him, he touched the socket of his thigh; so the socket of Jacob’s thigh was dislocated while he wrestled with him.
Ge 32:26 Then he said, "Let me go, for the dawn is breaking." But he said, "I will not let you go unless you bless me."
Ge 32:27 So he said to him, "What is your name?" And he said, "Jacob."

Twenty years earlier Jacob had lied to his father, and told him that he was Essau. Essau was a very hairy man, and Jacob's mother helped him trick his father by putting goat skins on him. Isaac, who was nearly blind, was tricked, but remarked the, "the voice is Jacob's but the skin is Essau's. After lying several times the trick seems to have succeeded, now twenty years later Jacob wrestles with a man we believe to be Jesus (the theological term is a theophany - an old testament appearing of Jesus).  Jesus asks him, "what is your name?" You see God will always bring you back to the place you first left the road. He will always use memory and conscience to remind you of the day you started down the wrong track. It is only as we 'fess up that we can get back to where we ought to be. Jacob rights his wrong, by confessing, "my name is Jacob." Lies will chase you down the corridors of your mind, till you finally get back to the place you left the road, only this time you start walking on the right foot. Keep the fire burning. The Truth will set you free.
