To us, He is our God and mediator with the Father.<quoted text>So Jesus was a lesser God or a god as Jehovah's witness believe also.
This bible verse contradicts what you are saying. Why?
I am the LORD, and there is no other; apart from me there is no God.
"This is what the LORD says-- Israel's King and Redeemer, the LORD Almighty: I am the first and I am the last; apart from me there is no God.
I have said, Ye are gods; and all of you are children of the most High.
Jesus answered them, Is it not written in your law, I said, Ye are gods?
Notice Jesus said that He said what was in their law. Jesus is the God of the Old Testament.
And Jesus made it very clear that He was subject to the Father. He prayed to the Father. He told us that He could do nothing that He didn't see the Father do. But to us, He is everything.
