Matthew 16:16-18
16 And Simon Peter answered and said, Thou art the Christ, the Son of the living God.
17 And Jesus answered and said unto him, Blessed art thou, Simon Barjona: for flesh and blood hath not revealed it unto thee, but my Father which is in heaven.
18 And I say also unto thee, That thou art Peter, and upon this rock I will build my church; and the gates of hell shall not prevail against it.
Peter found the rock that we must all build our faith. Christ was not saying that Peter was to be the church. He was saying that by realizing that he was the son of God, he had found the messiah. Our first step in becoming a part of the church is by accepting that Jesus is the only begotten Son of God and that he died for our sins. He is the only way into heaven. If we start our foundation with him, then nothing can tear us down. That rock that our foundation sets on is our faith that Christ is still setting at the right hand of the father, making intercession for us. So, build your foundation on the rock that is Jesus Christ.
