That is a misquote, or deliberate falsifying of Scripture (I'd prefer to assume it was a mistake). You didn't give a Bible reference, so I'll do it for you:
John 1:18 (WEB): No one has seen God at any time. The one and only Son, who is in the bosom of the Father, he has declared him.
It does not say that Jesus is God. "In the bosom of the Father" indicates that God and Jesus had an intimate, loving relationship. Their relationship is clearly stated - Jesus was God's one and only son. Note John later said:
John 6:46) Not that anyone has seen the Father, except he who is from God. He has seen the Father.
which also does not say Jesus is God, but it's clear that "he who is from God" is not God.
Surely you're not claiming that because Jesus came down from heaven that he must be God? Satan came down from heaven too - do you think he is God?!
And yet neither of those verses teach or prove that Jesus was God, and definitely don't teach the Trinity doctrine.
No, it isn't how our mind is renewed, that's done by correctly understanding the verses, which you have not done for the above verses.
1 John 4:14-15 (WEB): We have seen and testify that the Father has sent the Son as the Savior of the world. Whoever confesses that
Jesus is the Son of God, God remains in him, and he in God.
Luke 10:22) Turning to the disciples, he said, “All things have been delivered to me by my Father. No one knows who the Son is, except the Father, and who the Father is, except the Son, and he to whomever the Son desires to reveal him.”
