From the Gospels:

John 1: 1 – 14
In the beginning was the Word, and the Word was with God, and the Word was God. The same was in the beginning with God. All things were made by Him; and without him was not anything made that was made. In Him was life; and the life was the light of men. And the light shineth in the darkness; and the darkness comprehended it not. There was a man sent from God, whose name was John. The same came for a witness of the Light, that all men through Him might believe. He was not the Light, but was sent to bear witness of that light. That was the true Light, which lighteth every man that cometh into the world. He was in the world, and the world was made by Him, and the world knew Him. not. He came unto His own, and His own received Him not. But as many as received Him, to them gave He power to become the sons of God, even unto them that believe on His name: Which were born, not of blood, nor of the will of the flesh, nor of the will of man, but of God, And the word was made flesh, and dwelt among us, (and we beheld His glory, the glory as of the only begotten of the Father,) full of grace and truth.

Jesus is the image of the invisible God

Hebrews 1:3-The Son is the radiance of Gods glory and the exact representation of his being,sustaining all things by his powerful word. After he had provided purification for sins, he sat down at the right hand of the Majesty in heaven.

2 Corinthians 4:4 – The god of this age has blinded the minds of unbelievers, so that they cannot see the light of the gospel of the glory of Christ, who is the image of God.

Comment:
According to John 4:24, “God is spirit.” Luke 24:39 tells us “a spirit has no flesh or bone.” All scripture confirms that God in the Old Testament was invisible. “No man has seen God” (John 1: 18); but Jesus is described as the “exact representation of God, the image of God, and the image of the invisible God.”
