In this verse, Peter claims he will lay down his life for Jesus, contradicting his subsequent denial as depicted in Matthew 26:75.
John 13:37: Peter said unto him, Lord, why cannot I follow thee now? I will lay down my life for thy sake.
Contradiction with Luke 22:33
Peter asserts his readiness to go to prison and to death with Jesus, which stands in stark contrast to his denial in Matthew 26:75.
Luke 22:33: And he said unto him, Lord, I am ready to go with thee, both into prison, and to death.
Contradiction with Matthew 10:33
This verse states that denying Jesus before men will lead Jesus to deny them before His Father, creating a contradiction with Peter's ultimate restoration despite his denial in Matthew 26:75.
Matthew 10:33: But whosoever shall deny me before men, him will I also deny before my Father which is in heaven.
