How do we know Jesus Christ is the revelation of God?

In Scripture, particularly in the Gospel of John, it is affirmed that Jesus is the manifestation of God. No one has seen God at any time, but the only begotten Son, who is in the bosom of the Father, has declared Him. Jesus explicitly states that seeing Him is tantamount to seeing the Father. This reveals the unique role of Christ in disclosing divine truths to humanity, as He encompasses all that God is. The fullness of the Godhead dwells in Him bodily, and His teachings and actions throughout the Gospels reflect the character and purposes of God, thus affirming Him as the ultimate revelation of God.
