I wrote Monday about the importance of knowing who we are in Christ and the identity change that happens when we do. Up until the last few weeks, I'd never thought about this.
Simon's name was changed to Peter, which means "a piece of the rock," which is a revelation of who Jesus is. When Peter had his light bulb moment, he looked at Jesus and said in Matthew 16:16-19, "You are the Christ, the Son of the living God." Jesus turned and looked at Peter and said, "Flesh and blood did not reveal this to you. My Father revealed this to you." After Peter identified Jesus, Jesus told Peter in verse 18, "Thou art Peter, and upon this rock I will build my church; and the gates of hell shall not prevail against it." Jesus changed Peter's name, his character, his destiny and his possibilities in life. Everything changed for Peter.
The moment we see who Jesus is, He tells us who we are. And being a Christian is not about having a behavioral change every day, but having a heart change.
