There are many Bible verses that link the Divine Nature of our Lord Jesus The Christ within the Divine Nature of The Father. The LORD didn't ask us to understand that, He asked us to believe it as He said.
John 14:6-11
6 Jesus saith unto him, I am the way, the truth, and the life: no man cometh unto the Father, but by Me.
7 If ye had known Me, ye should have known My Father also: and from henceforth ye know Him, and have seen Him.
8 Philip saith unto Him, "Lord, shew us the Father, and it sufficeth us."
9 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?'
10 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.
11 Believe Me that I am in the Father, and the Father in Me: or else believe Me for the very works' sake.
(KJV)
Truly, if one thinks our Lord Jesus was a man only, then why can't other men be a Saviour also? Why can't others be "in the Father" and The Father in them?
THERE'S THE RUB...
In the pagan mystery schools of initiation throughout history, the idea that man can become his own god was part of their ancient belief. That idea began with the serpent in Eden (Gen.3). That false idea is still being taught by the fraternities of mystical initiation today. Their teaching must delegate our Lord Jesus Christ down to being only a man and not co-equal with God The Father, because they do not want to admit that only Jesus of Nazareth is God The Saviour, born through woman's womb by The Holy Spirit. Nor do they want to admit that we all must go through Christ Jesus for Salvation. Jesus Christ is the ONLY Mediator to The Father. Instead, they teach we can save ourselves by becoming 'Christ-like', actually becoming our own 'Christ'.
I'm not joking about that false teaching among the mystery school initiates. The old doctrines of Gnosticism is part of that idea, since they believed that our Lord Jesus did not actually die on the cross, but that His disciples removed His body off the cross beforehand. Their teaching includes the idea of self-perfection through mystical exercises and ascetic living, trying to become god-like. They only recognize Jesus as a highly developed spiritual "adept" or "avatar". Within that is a belief that around every 2,000 years God sends His Spirit to earth through a highly developed person ("avatar") to slowly prepare peoples in the world for a return to some ancient Atlantis-type utopian reality (seen the movie Avatar? That's not a new theme. It's an old theme from the pagan mysteries). They claim our Lord Jesus was only one of several avatars, others being Buddha, Zoroaster, Krishna, Muhammed, etc., basically the founders of the world's major religions of history.
They claim that is possible with the idea of a Christ-Spirit, or Christ-Consciousness, like a force in the universe that anyone may atone to, and become an "adept" master (sound like oriental philosophy? It's included in their system). Per that, Buddha, Zoroaster, Muhammed, Confuscious, Krisha, and even our Lord Jesus simply atoned to that Christ-Consciousness in the sky, and became highly spiritual adept masters.
This is why they cannot admit that our Lord Jesus Christ is God, like Isaiah 9:6 does declare Jesus as The Father also. If they admitted Jesus is God The Saviour, then where would that leave Buddha, Zoroaster, Muhammed, etc.? It would reduce the effect of those religions that treat them as holy prophets, and elevate our Lord Jesus above them if it was admitted that Jesus was more than just a prophet, and more than human.
This is why one of their 'tells' is the false belief that ALL religious paths lead to the same God and same Salvation. That's why they hate when we true Christians declare that Jesus Christ is the ONLY WAY of Salvation to GOD The Father. Christ Jesus did die on the cross as witnessed by His Apostles and disciples, and The Father raised Him from the dead as also witnessed by Christ's Apostles and disciples. None other in any other religion has done that. Our Heavenly Father made certain Jesus The Christ's Blood shed upon the cross would be the only True Mark of His Promised Salvation. Any other way will not measure up.
Just think, per the mystery schools of initiation, YOU can become your OWN Christ, simply by tuning into the force of Christ-Consciousness like the man Jesus did! You don't really need Jesus per their view. You can become your OWN Jesus, and even do your OWN Salvation!
Every time someone tries to claim our Lord Jesus Christ was only a human man, and not God The Son, Emmanuel (God with us) as written, then that old false pagan mystery school belief comes to mind.
