In this chapter we see Jesus chiding his disciples with the words, “…you of little faith.” And then a little later, He asks a question to test their faith. “Who do you say that I am?”
Peter, that passionate impulsive man that he is says, “You are the Christ, the Son of the Living God!”
Jesus said to Peter, “Blessed are you, Simon son of Jonah, because flesh and blood did not reveal this to you, but my Father who is in heaven.”
In this scene, Jesus is not pronouncing a blessing on Peter. He is observing that Peter is already blessed. Why is Peter blessed? Because God the Father has revealed to him that Jesus is the Christ, the Son of the living God. This is a well-known moment in church history, because it is here that Jesus first reveals His plan to build a church.
Remember, this chapter is about faith. Jesus declares here that Jesus will build His church on the faith given to man by God. Can you make the same confession as Peter? Do you believe that Jesus is the Christ, the Son of the Living God? Then you, too are blessed. 1 Corinthians 12:3 says, “No one is able to say “Jesus is Lord” except by the Holy Spirit.
Sure, anyone can say the words, but no one can believe them unless the truth is revealed to them by God. If you believe, you…like Peter…are blessed.
