Jesus claimed this and Jesus claimed that, carries no weight.<quoted text>
No one has ascended to heaven but He who came down from heaven, that is, the Son of Man who is in heaven. And as Moses lifted up the serpent in the wilderness, even so must the Son of Man be lifted up, that whoever believes in Him should not perish but have eternal life(John 3:13-15).
In this passage, Jesus issued four unmitigated affirmations of His divine identity:(1) He claims to have come from heaven,(2) He claims to be an eternal resident of that heavenly realm,(3) He further claims that He is the source of healing comparable to the snake on the pole in Numbers 21, and (4) He claims that in order for a person to have eternal life and thereby avoid perishing, that person must believe in Him.
The expression son of man occurs only one time in the Old Testament to refer exclusively to Jesus, the Messiah: Daniel 7:13. Herein likely lies the deeper significance of Jesus use of the term. It is to this verse that Jesus linked Himself when He came to Earth:
I was watching in the night visions, and behold, One like the Son of Man, coming with the clouds of heaven! He came to the Ancient of Days, and they brought Him near before Him. Then to Him was given dominion and glory and a kingdom, that all peoples, nations, and languages should serve Him. His dominion is an everlasting dominion, which shall not pass away, and His kingdom the one which shall not be destroyed (Daniel 7:13-14).
Son of God?
Therefore the Jews sought all the more to kill Him, because He not only broke the Sabbath, but also said that God was His Father, making Himself equal with God. Then Jesus answered and said to them,Most assuredly, I say to you, the Son can do nothing of Himself, but what He sees the Father do; for whatever He does, the Son also does in like manner. For the Father loves the Son, and shows Him all things that He Himself does; and He will show Him greater works than these, that you may marvel. For as the Father raises the dead and gives life to them, even so the Son gives life to whom He will. For the Father judges no one, but has committed all judgment to the Son, that all should honor the Son just as they honor the Father. He who does not honor the Son does not honor the Father who sent Him. Most assuredly, I say to you, he who hears My word and believes in Him who sent Me has everlasting life, and shall not come into judgment, but has passed from death into life. Most assuredly, I say to you, the hour is coming, and now is, when the dead will hear the voice of the Son of God; and those who hear will live. For as the Father has life in Himself, so He has granted the Son to have life in Himself (John 5:18-26).
What matters is what he declared?
And we do not see him declaring from his own mouth in integrity, anything such as "I am the son of God" or "I am God in person" or "I am God".
Jesus is not on record for making any statement claimed for him, himself. That is the point.
You wrote and I quote: "Therefore the Jews sought all the more to kill Him, because He not only broke the Sabbath, but also said that God was His Father, making Himself equal with God."
Interesting! God was only his Father? God was everybody's Father then.
Jesus never said, "God is my father". Writing His Father does not make God his father and neither does the capital H in his, makes him God.
However, he also said this to Mary (john 20:17), when she had wanted to cling to him but he stopped her:
"Go instead to my brothers and tell them,I am going to my Father and your Father, to my God and your God.
Why not make Mary and the disciples (his brothers) Gods too?
