(Read Matthew 26:31-35.)
Jesus tells the disciples that they're all going to abandon Him, and then tells them He'll be in Galilee waiting for them.
Jesus tells Peter that Peter is going to deny Him, but doesn't dismiss Peter from being His disciple.
Jesus knew the disciples were going to mess up, and He would be waiting for them when it was all over. Jesus is the same with us. He knows we're going to make mistakes, but He never sends us away from Him or tells us we can't be His disciples anymore. He just waits for us to come back to Him and try again. How amazing He is.
