What I'm finding in the Body of Christ is our refusal to allow God to conform us to His Image. This means that because our ways aren't His Ways and our thought process is contrary to His, that we like Jacob are wrestling with God to stay the same. We don't want the Lord to change our habits, routines, ways of thinking, religious traditions....etc. We like Peter are trying to follow Christ but not applying the Cross in our Walk/Living for Him. In order to live for Him, we must obey His Word so that we can grow up to become a perfect/mature man/woman of God.
