Luke 18:19
"And Jesus said unto him, Why callest thou me good? none is good, save one, that is, God."
If Jesus is God, why does he say that?
John 20:17
"Jesus saith unto her, Touch me not; for I am not yet ascended to my Father: but go to my brethren, and say unto them, I ascend unto my Father, and your Father, and to my God, and your God"
Also, Jesus is also referred to as the Son of Man. God is obviously not the Son of Man.
Psalm 8:4
"What is man, that thou art mindful of him? and the son of man, that thou visitest him?"
Yes they are indeed one but they are also individuals.
Hebrews 5:5
"So also Christ glorified not himself to be made an high priest; but he that said unto him, Thou art my Son, to day have I begotten thee."
1 Corinthians 11:3
"But I would have you know, that the head of every man is Christ; and the head of the woman is the man; and the head of Christ is God."
There are plenty of verses that show you that are individuals. Here are some that show you they are one and abide in each other.
John 1:1-4
"
1 In the beginning was the Word, and the Word was with God, and the Word was God.
2 The same was in the beginning with God.
3 All things were made by him; and without him was not any thing made that was made.
4 In him was life; and the life was the light of men.'
John 14:9-10
"Jesus saith unto him, Have I been so long time with you, and yet hast thou not known me, Philip? he that hath seen me hath seen the Father; and how sayest thou then, Shew us the Father?"
"Believest thou not that I am in the Father, and the Father in me? the words that I speak unto you I speak not of myself: but the Father that dwelleth in me, he doeth the works."
Jesus did not come to do his own will, but the Father's will who sent him. God dwells in Jesus and they abide in each other but Jesus made it clear that he was honoring the Father, was sent by the Father, and that God is the one who does the works. They aren't the same person
