The very first verse of the Book of Revelation gives us a clue as to the answer:
“The revelation from Jesus Christ, WHICH GOD GAVE HIM to show his servants what must soon take place” (Revelation 1:1 NIV).
“And from Jesus Christ, who is the faithful witness, the first born from the dead . . . and has freed us from our sins by his blood” (Revelation 1:5 NIV).
If Jesus was God, he would not have to be given the revelation by God.
Jesus cannot be Almighty God because he died, and Almighty God “never dies” (Habakkuk 1:12 NJB).
“And has made us to be a kingdom and priests to serve his God and Father” (Revelation 1:6 NIV).
Jesus is described as having “his God and Father”. Therefore, he cannot be equal to God the Father.
