In Mark 14:37, Jesus finds Peter sleeping in Gethsemane – failing to watch, contrary to his bold assertion.

In Mark 14:68, Peter denies knowing Jesus – the direct opposite of his vow to never be offended.

In Mark 14:54, Peter follows at a distance into the courtyard – showing fear, not the steadfastness he claimed.

Matthew 26:33-35 records Peter's vehement declaration of loyalty, contrasting his confidence with Jesus' prediction of denial.

Luke 22:33 has Peter boasting he is ready to follow Jesus to prison and death, echoing his overconfidence.

In John 13:36-38, the same dialogue appears: Peter vows to die for Jesus, and Jesus predicts his denial.

In John 21:15, Jesus restores Peter after his denial – a direct contrast to Peter's boastful claim here.
