And the Lord said, Simon, Simon, behold, Satan hath desired to have you, that he may sift you as wheat: But I have prayed for thee, that thy faith fail not: and when thou art converted, strengthen thy brethren. And he said unto him, Lord, I am ready to go with thee, both into prison, and to death. And He said, I tell thee, Peter, the cock shall not crow this day, before that thou shalt thrice deny that thou knowest me. – Luke 22:31-34

In Luke 22:33 Peter “thought” he was ready to go with Jesus to prison and to death, but Jesus let him know he was about to deny Him 3 times!

Jesus assured Peter that even though his faith might falter, it would not fail! It would be renewed and Peter would go on to be a powerful leader!
