Why did Jesus say that the writings of Moses were his words? Answer: Cause Jesus is the Word of God. Just like it says in the book of John. In the beginning was the Word, and the Word was with God, and the Word was God. And the word was made flesh and dwelt among us.

"And without controversy great is the mystery of godliness: God was manifest in the flesh, justified in the Spirit, seen of angels, preached unto the Gentiles, believed on in the world, received up into glory."

When was God manifest in the flesh?
