What does the Bible say about Peter's denial and repentance?

The Bible recounts Peter's denial of Jesus in Matthew 26:69-75, where he dramatically denies knowing the Lord three times. Following this, in Luke 22:61-62, Peter experiences profound remorse, weeping bitterly over his failure. This moment serves as a significant turning point, illustrating the reality of human frailty and the depth of forgiveness in Christ. Peter's bitter tears symbolize true repentance, which is granted by God and can lead to restoration and renewed purpose. He is ultimately restored and becomes a powerful instrument in advancing the gospel, as seen in Acts.
