The story of Jacob (Genesis 32:22-31) wrestling with the Angels is well known. Here is a picture of prayer in action.
What was happening that night was first of all God’s faithful dealing with recalcitrant Jacob until he absolutely came to the end of himself and was forced to depend wholly on God. The other part of the story concerns Jacob’s perseverance in prayer, holding on to God, until God bless him.
What an awesome encouragement to us today.
