But Peter said, “Man, I do not know what you are talking about.” And immediately, while he was still speaking, the rooster crowed. And the Lord turned and looked at Peter. And Peter remembered the saying of the Lord, how he had said to him, “Before the rooster crows today, you will deny me three times.” And he went out and wept bitterly. Luke 22: 60-62
What did Peter just do? How could he deny Jesus after all they had been through? This was the lowest moment of his life. He had failed miserably. Peter didn’t have faith that Jesus would take care of him. He was only thinking about himself.
