And the LORD, having turned, looked on Peter, and Peter remembered the word of the LORD, how He said to him, “Before a rooster will crow, you may disown Me three times”; and Peter having gone outside, wept bitterly Luke 22.61-62

Peter denied his Lord three times and then the Lord Looked Upon him.

That Look of Jesus Broke the heart of Peter, and all at once there Opened Up Before him the terrible sin that he had committed, the terrible failure that had come and the depth into which he had fallen,

And Peter went out and Wept Bitterly.
