"But what about you?" he asked. "Who do you say I am?" Simon Peter answered, "You are the Messiah, the Son of the living God."
Jesus replied, "Blessed are you, Simon son of Jonah, for this was not revealed to you by flesh and blood, but by my Father in heaven. And I tell you that you are Peter, and on this rock I will build my church, and the gates of Hades will not overcome it. I will give you the keys of the kingdom of heaven; whatever you bind on earth will be bound in heaven, and whatever you loose on earth will be loosed in heaven" Matthew 16:17-19. This is the moment Christ revealed to Peter part of his identity. In verse 17, Jesus calls him Simon, but in the next verse He declares that You are Peter which means rock or stone. And stone symbolizes foundation or something to build from. And certainly Peter was a foundational piece of the early church. As a matter of fact, he was one, if not the lead disciple. How do I know? Peter was always mentioned first when listed among the disciples. Why is this proof? Well, Judas Iscariot (betrayed Jesus) was always mentioned last. And once Peter received identity confirmation, Christ gave him the keys to the Kingdom and proclaimed that the gates of Hades (hell) would not prevail against it.
We go through the motions of Christianity without ever getting a true revelation of Christ from God in heaven. I call it identity crisis because we are confused about who Christ is and our identity in Him. Let's stop operating as orphans and function as sons and daughters. So again Jesus asks, "Who do you say I am?"
