Then how can Jesus be G-d? Jesus was a human who had flesh and blood.
Jesus did not become God.
Scripture tells us that God became God in the flesh as Jesus Christ-—He was fully God, and fully man. This incarnation was His choice and His doing.
But it also tells us that God is eternal and almighty, with no beginning and no end. That puts to rest the Mormon teaching that He began as a plain human being and somehow “became” a god.
The former shows the power of the creator God, while the latter falsely teaches of a semi-deity whose beginning is no different from our own. IMO, the purpose of that teaching plays to human pride.....it says, see, God used to be nothing more than a man, so you can aspire to be a god, too.
