I'm sorry, you seem to be oblivious as to how many times that you jumped to unwarranted conclusion, just in that one paragraph.
So, that's it, Thomas said 'my Lord, and my God', therefore, the man standing before him was the almighty, omnipresent and transcendent God?
Horrible, horrible exegesis!
I think unbelief is your problem.
Thomas saw all Jesus's ministry and knew Jesus said He would rise again. But as this was impossible, even when the other disciples said it happened he could not accept it.
So Thomas finally admits Jesus is God.
Jesus said to Lazarus, even if people rise from the dead, they will not accept the reality.
Emotional conviction can be wrong. I walked once into a bog/swamp. It looked safe to continue but I was sinking. So I was wrong, what I was sure was safe would kill me. What I did know was reversing my steps was safe. So that is what I did.
No man could be God, until God appeared in human form. If this man was so unusual then maybe. And it's the maybe that opens the door.
Some have no maybe, because they know, except everything we know is faith based, there is no absolute knowledge possible. God bless you
