Life of Peter... (ex: denial of Jesus)
Jesus is modeling how mercy puts a nuance on justice. We act justly, so we can show mercy.
Mercy is not commending. At no point does Jesus say, “What you did Peter, was right.” Or even, “I get it, we all make mistakes.” He acknowledges what was wrong. He calls it out. Then he offers mercy.
Mercy is not forgetting. Jesus had not forgotten what Peter had done. He addressed it. And then moved on. Granting mercy to someone in your life allows the relationship to continue, but it may take time for you to forget what has happened. If ever.
