Can you read those scriptures you posted...
'No one has ever seen God' How can God be Jesus if no one has ever seen him?
The Jews objected to Jesus claim that he had come from heaven. Thats what they objected to. Never did they think he was God.
According to John 5:37, Jesus said that no one had ever seen God at anytime or ever heard his voice. And yet people did see Jesus, which proves that Jesus cannot be God.
That's the point your trying to make right?
As it is often the case in polemical arguments, the paraphrase of the passage misrepresents Jesus’ words in several ways. Jesus did not make a general statement ("no one ever") but addressed a particular group of people ("you"). Moreover, he spoke about the Father, not about God in general. Since Jesus is the Son, not the Father, the above conclusion is invalid. Here is what that passage actually says:
"And the Father who sent me has himself testified concerning me. You have never heard his voice nor seen his form, nor does his word dwell in you, for you do not believe the one he sent." John 5:37-38
The questioner is assuming that Jesus meant that no one at any time has seen God or heard his voice, when in actuality his comments were addressed to a specific group, not to everyone. Jesus was saying that those specific Jews whom he was directly addressing hadn't seen or heard God. But even here Jesus clearly says that the Father has testified concerning him, implying that God had indeed spoken and revealed himself in some way to people in order to testify on behalf of his Son.
The following Scriptures explicitly state that many have both seen and heard from God:
"Micaiah continued, 'Therefore hear the word of the LORD: I saw the LORD sitting on his throne with all the host of heaven standing around him on his right and on his left.
1 Kings 22:19
"In the year that King Uzziah died, I saw the Lord seated on a throne, high and exalted, and the train of his robe filled the temple..."
Isaiah 6:1-8
"As I looked, thrones were set in place, and the Ancient of Days took his seat. His clothing was as white as snow; the hair of his head was white like wool. His throne was flaming with fire, and its wheels were all ablaze. A river of fire was flowing, coming out from before him. Thousands upon thousands attended him; ten thousand times ten thousand stood before him. The court was seated, and the books were opened." Daniel 7:9-10
To summarize, the passage is not denying that people have seen or heard from God. It is simply stating that those particular Jews, whom the Lord Jesus was addressing, showed through their unbelief that God hadn't enabled them to accept and realize the fact that the Person standing before them was God's self-revelation to them. In other words, it wasn't that God hadn't made himself known to them, since he definitely had in the Scriptures and through the Person and work of Christ. But that, despite the revelation they were receiving, God hadn't set them free from their spiritual blindness in order to be able to discern the fact that he was clearly speaking to them in his Son.
