The Penitent Thief, also known as the Good Thief or the Thief on the Cross, is one of two unnamed persons mentioned in a version of the Crucifixion of Jesus in the New Testament. The Gospel of Luke describes one asking Jesus to "remember him" when Jesus will have "come into" his kingdom. The other, as the impenitent thief, challenges Jesus to save himself to prove that he is the Messiah
