There's just so much here.
Consider the two failures of the two men who were close to Jesus. On the one hand, Judas betrayed Him for money. On the other hand, Peter betrayed Him for safety. Both felt sorry, Judas so much so that he gave his prize money back. Peter wept bitterly. I wonder if that made the difference in his spiritual future. He wept over his sin.
Just earlier we read about those being ashamed of Jesus in the coming age will be surprised by His shame of them. But Peter repented, weeping bitterly. Tears mattered. And restoration came, with ministry as a founder of the church soon on its heels.
No matter who you are, no matter what you've done, Jesus takes the broken lives of those who have betrayed Him (which is all of us) and come to Him. He receives us and makes us whole.
