Genesis 32:26. "And Jacob replied, I will not let you go unless you bless me."
I never really thought about how powerful that verse is. Jacob did not know he was wrestling with God Himself, but I doubt his response would have been any different. He spent the entire night wrestling with God for a blessing.
I know I don't have that kind of dedication--but I want it. I want to cling to God, pray to Him, seek His will, hold fast and say "I will not let go unless you bless me!"
After all, it's what He wants to do. He just wants us to ask.
