Thank God that the Holy Spirit is able to reveal to us "Who is Christ."

............In Matthew 16:15
Jesus asks His disciples,
............"But whom say ye that I am?"
Peter replied,
............"Thou art the Christ, the Son of the living God."

............Jesus said,
"Flesh and blood hath not revealed it unto thee, but my Father which is in Heaven."

............The Father, by the Holy Spirit opened Peter's mind to understand that Jesus of Nazareth was the Christ of God.
