Paul's Metaphor of the Old Man and the New man

Paul uses the metaphor of the “old man” and the “new man” to help explain what Christ did for us in His crucifixion.  Jesus was fully God.  Because He was also fully Human, His death was our death (Romans 6:6), His resurrection was our resurrection (2 Corinthians 5:17).
