A Perfect Library

Your mind may be a perfect library of the opinions of men, and you will still be no nearer the truth than were those wise men among Israel. They were all wrong. "Whom say ye that I am?" In this your salvation rests—not in your acquaintance with the opinions of men.
“Whom say ye that I am?" Peter answers. "Thou art the Christ." We know from the Gospel of John that it was this that first engaged the heart of Peter. Philip says. "We have found Him. of whom Moses in the law, and the prophets, did write, Jesus of Nazareth, the son of Joseph." John 1:45. He was the fulfiller of 311 God's promises, the anointed One, the Messiah.
John refers to this as being the cardinal point with the soul that knows God when he says. "Whosoever believeth that Jesus is the Christ is born of God.”
John 5:1. You may believe many things about Him. but unless you believe Him to be the fulfiller of all God's promises in connection with His people, and the anointed One of the Holy Spirit whom God proclaimed to be His own San, then you are not born of God, however upright and good you may be. The spark is absent from your soul, which makes all the difference between those who are dead in trespasses and sins, and those who are alive in Him.
Peter had heard of the Father's own message concerning His Son at the waters of Jordan.
