Jesus knew it, too. I do not know him . As soon as the words were out of Peter's mouth, as soon as he heard the cock crow, Jesus looked at Peter from across that courtyard. That will not be possible. He cannot undo the hurt he has caused.
Nails driven into flesh leave their mark.
But if Jesus is alive, that night of betrayal can become the bridge to a new life for Peter. Peter will always be the apostle who denied the Lord, but that very denial, borne by Christ upon the cross, can become for Peter the keys to the kingdom of grace. If Jesus is alive, then God's healing forgiveness is alive, too. I'll tell you something. There are moments in my life when I pray the same prayer.
