18 No man hath seen God at any time, the only begotten Son, which is in the bosom of the Father, he hath declared him.
If no man hath seen God, then who is the Jesus they hath seen?
If you had known Me, you would have known My Father also; and from now on you know Him and have seen Him. Philip said to Him, Lord, show us the Father, and it is sufficient for us. Jesus said to him, Have I been with you so long, and yet you have not known Me, Philip? He who has seen Me has seen the Father; so how can you say, Show us the Father? Do you not believe that I am in the Father, and the Father in Me? The words that I speak to you I do not speak on My own authority; but the Father who dwells in Me does the works. Believe Me that I am in the Father and the Father in Me, or else believe Me for the sake of the works themselves. (John 14:7-11 NKJV)
Interesting how you should mention that no one "had" seen God, ho theos, a title that can be used for the Father, however, God is also Lord, Jesus is Lord, Jesus is God.
Nt writers did this in order to assign both deity to The Father and the Son, but not to confuse people as to say the Son is the Father in personage, in addition to being. Hence Jesus is called "Lord", and Thomas also calls him, "God".
As for no man having seen ho theos, that refers to no man having seen God, the Father in the Past, not that they never saw God, the Son.
My next point is critical, and you ought to address it:
People, while not seeing ho theos, as to say The Father, they did see God.
Then Moses went up, also Aaron, Nadab, and Abihu, and seventy of the elders of Israel, and
they saw the God of Israel. And there was under His feet as it were a paved work of sapphire stone, and it was like the very heavens in its clarity. But on the nobles of the children of Israel He did not lay His hand.
So they saw God, and they ate and drank. (Exodus 24:9-11 NKJV)
Then Jacob was left alone; and
a Man wrestled with him until the breaking of day. Now when He saw that He did not prevail against him, He touched the socket of his hip; and the socket of Jacobs hip was out of joint as He wrestled with him. And He said, Let Me go, for the day breaks. But he said, I will not let You go unless You bless me! So He said to him, What is your name? He said, Jacob. And He said, Your name shall no longer be called Jacob, but Israel; for
you have struggled with God and with men, and have prevailed. Then Jacob asked, saying,
Tell me Your name, I pray. And He said, Why is it that you ask about My name? And He blessed him there. So Jacob called the name of the place Peniel:
For I have seen God face to face, and my life is preserved. (Genesis 32:24-30 NKJV)
And the Angel of the Lord said to her: Behold, you are with child, And you shall bear a son. You shall call his name Ishmael, Because the Lord has heard your affliction. He shall be a wild man; His hand shall be against every man, And every mans hand against him. And he shall dwell in the presence of all his brethren. Then she called the name of the Lord who spoke to her, You-Are-the-God-Who-Sees; for she said, Have I also here seen Him who sees me? (Genesis 16:11-13 NKJV)
Then Manoah said to the Angel of the Lord, What is Your name, that when Your words come to pass we may honor You? And the Angel of the Lord said to him, Why do you ask My name, seeing it is wonderful? So Manoah took the young goat with the grain offering, and offered it upon the rock to the Lord. And He did a wondrous thing while Manoah and his wife looked on it happened as the flame went up toward heaven from the altarthe Angel of the Lord ascended in the flame of the altar! When Manoah and his wife saw this, they fell on their faces to the ground.
When the Angel of the Lord appeared no more to Manoah and his wife, then Manoah knew that He was the Angel of the Lord. And Manoah said to his wife, We shall surely die, because we have seen God! But his wife said to him, If the Lord had desired to kill us, He would not have accepted a burnt offering and a grain offering from our hands, nor would He have shown us all these things, nor would He have told us such things as these at this time. (Judges 13:17-23 NKJV)
The God of the Old Testament, is Jesus, the Commander of the Armies of the Lord.
