This will be a short post, just to show you a verse in which the Father calls Jesus, the Son, “God”.
“But unto the Son he saith, Thy throne, O God, is for ever and ever: a sceptre of righteousness is the sceptre of thy kingdom.” (emphasis added)
There, that’s the Father talking to the Son, Jesus. See what He calls Him? God.
“Looking for that blessed hope, and the glorious appearing of the great God and our Saviour Jesus Christ;” (emphasis added) Yeah, you read that right. Jesus is called the great God and Saviour. Case closed.
