Jacob wrestled with God and became an overcomer (Genesis 32:28). Christ wrestled with the powers of evil, and has won a mighty victory for us.
When He cried out from the Cross, ‘It is finished’ (John 19:30), this was not an admission of defeat. It was the declaration of victory - the victory has been won, the victory is complete. ‘Thanks be to God who gives us the victory through our Lord Jesus Christ’ (1 Corinthians 15:57).
For Jacob, crossing the Jabbok involved a spiritual ‘crossing over’. Jacob became Israel, a new man (Genesis 32:28).
After he had been ‘touched’ by God, Jacob was ‘limping’ (Genesis 32:31-32). This was a reminder of his own weakness.
His true strength was in the Lord. Wait on the Lord, and renew your strength (Isaiah 40:31).
