Correct!

And Simon Peter answered and said, "Thou art the Christ, the Son of the living God." And Jesus answered and said to him, "Blessed are you, Simon Barjona, because flesh and blood did not reveal this to you, but My Father who is in heaven." Matthew 16:13-17 (NAS)

This fact (that Jesus was the Christ, the son of the living God) was not revealed by anyone or anything having "flesh and blood" (verse 16 says "flesh and blood did not reveal this...".)  It it was revealed by God...the Father of Jesus.
