In Luke 22:31-34 Jesus foretold Peter’s failure. Despite his bold assertion that he, of all people, would never fail to follow Jesus before the night was finished he would deny Jesus three times. The text reveals that Satan attempted to undermine the entire band of followers by causing Peter to fall away. But Jesus interceded on Peter’s behalf, thus preserving him from ultimate failure. He also predicted that Peter would be restored and be made useful in Jesus’ service.
