What does the Bible say about Peter's denial of Jesus?

In the Gospel of John, the narrative describes Peter's denial as a significant moment of weakness. After boldly declaring he would never forsake Jesus, Peter ultimately succumbed to fear in the face of questioning from a servant girl and others. The emotional toll of this denial led Peter to weep bitterly, showcasing the contrast between his initial confidence and his actual failure when confronted in a moment of trial. This incident illustrates the fragility of human resolve and the need for divine grace in our lives, highlighting the importance of reliance on Christ rather than self-confidence.
