No man has seen God at any time
“No man hath seen God at any time; the only begotten Son, which is in the bosom of the Father, he hath declared him.” John 1:18
“No man hath seen God at any time…” I John 4:12
When Abraham spoke to God he was speaking to Christ, the same with Jacob when he says that he has “seen God,” he is referring to Jesus, as are the other examples where man has seen, or spoken to God.
In context, in John 1:18 and I John 4:12 we find that John is identifying the persons of God the Father and His beloved Son, and in so doing he is confirming that he is talking of the Father, that no man has seen. Therefore, we can conclude that it was the Son of God whom Jacob and the others had seen, and not the Father, this idea is supported throughout the Scriptures.
In Christ “all fullness” dwells, even “all the fullness of the Godhead bodily.” Godhead simply means “divinity”. As the Father is divine, so also is the Son, as He was brought forth from the Father. The Father is the God of all, and the source of all, but the Son has all the powers of the divine nature because He is of the same essence as the Father.
As legislator, Jesus exercised the authority of God; His commands and decisions were supported by the Sovereignty of the eternal throne. The glory of the Father was revealed in the Son; Christ made manifest the character of the Father. He was so perfectly connected with God, so completely embraced in his encircling light, that he who had seen the Son, had seen the Father. His voice was as the voice of God.
Notice Christ’s prayer before his crucifixion: “And now, O Father, glorify thou me with thine own self with the glory which I had with thee before the world was.” Again he says, “I am in the Father, and the Father in me.” “No man knoweth the Son but the Father; neither knoweth any man the Father save the Son, and he to whomsoever the Son will reveal him.” “He that hath seen me hath seen the Father.”
Therefore it is only possible for man to have seen the Father through the Son, as the Son is the perfect image or reflection of the Father.
And Jesus confirms: “And the Father himself, which hath sent me, hath borne witness of me. Ye have neither heard his voice at any time, nor seen his shape.” John 5:37
