"I will not let you go unless you bless me."

"Nothing in my hands I bring,
Only to Thy cross I cling."
Augustus Toplady

 For true blessing, we must wrestle, not with man, but with God, bringing nothing in our hands, but only clinging to His cross.

Genesis 32:26, 'Then he said, "Let me go, for the day has broken." But Jacob said, "I will not let you go unless you bless me."' Through out his life, Jacob had been struggling to gain the blessing by his own means. Now he clinging to the Lord.
