John 10:30
I and the Father are one.
John 14:9
Jesus answered: "Don't you know me, Philip, even after I have been among you such a long time? Anyone who has seen me has seen the Father. How can you say, 'Show us the Father'?
Hebrews 1:3
The Son is the radiance of God's glory and the exact representation of his being, sustaining all things by his powerful word. After he had provided purification for sins, he sat down at the right hand of the Majesty in heaven.
That's good enough for me.
Sadly, I can't see these as even implying Jesus is God, let alone prove it.
Jesus IS one with the Father, and it is our goal to be the same, but we will not become gods.
Anyone who sees Jesus sees the Father, because as your third verse says, the Son is the radiance of God's glory.
Also, we are told that we cannot see the Father, so seeing the Father reflected in Jesus is what we are given.
Also the third verse says an exact representation of His being, a representation instead of the actual since we are incapable of seeing the actual.
One more thing. John 14:6
Jesus answered, "I am the way and the truth and the life.
No one comes to the Father except through me."
Why would we need to go 'through' Jesus to get to God if Jesus is God?
I'm not trying to be a pain, just want to understand.
Some background:
My wife and I both came to know Jesus, NOT through a church setting. Her, decades ago, and me only a few years.
Neither of us ever had a concept of a trinity until a couple years ago when we decided to try to find a church.
We didn't think much of it, until we discovered it was VERY important to the church that we accept it.
Since I question everything in life, I started to do some research, and that's why I am at this baffling place, trying to figure out why most churches make this point such a big thing when as yet I cannot accept it as truth.
