Luke 22:33-34

Peter’s commitment to Jesus was admirable. Luke alone recorded that Peter promised to die with Jesus, and he made no reference to the other disciples. Nonetheless, Peter overestimated his own ability to remain faithful when persecuted. Luke is also the only evangelist who mentioned that Jesus told Peter that he would deny that he even knew Jesus. Perhaps this was a particular temptation for Theophilus and Luke’s original Greek readers. "Rocky" would hardly behave as a rock. His overconfidence should be a warning to every disciple.
