This will be a short post, just to show you a verse in which the Father calls Jesus, the Son, “God”.
Hebrews 1:8
“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.
Titus 2:13
“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.
