Peter put his faith in his Lord, although at first he seemed to struggle with external sins, and Jesus claimed that Peter did not always understand his teachings. He understood what the Holy Spirit revealed to him, and he followed his Lord. Even after betraying Jesus by denying him and failing to defend him at trial, he returned. He regretted it and it was better to move on. This example is one that Christians should follow today. Respond to God's call to follow Him, and then see Him through good times and bad. Sin and mistakes will happen, but God is ready to forgive. Two men, two betrayals, two different results with a single lesson: Jesus is Lord and He is willing to forgive us if we come to Him in faith and sincere repentance.
