God didn’t lose anything by wrestling Jacob. Jacob didn’t actually beat God. Jacob wins because he couldn’t grapple with something without being near it, in it, on it. When we wrestle with our understanding of God I think we get more of the Creator on us and in us. In Jacob's case he got a new name, Israel, which became the name of the whole Jewish people. The word “Israel” literally means, “He who wrestles with God wins.”
The problem became a blessing.
Know you are blessed,
