Tambora can't explain the things she says. Maybe you can help Tambora.
So if Jesus body and spirit is just a man---how do you get him lived in heaven before coming to earth, and how do you gather that he is God while on earth?
Tam does an excellent job on her own. You just can't hear her. You've got beans in your ears, or something.
The Lord Jesus is the 'theanthropic person'.
He is fully GOD/Theos.
He is fully man/Anthropos.
One person, two natures.
The Word which is GOD was Spirit but also a 'person'(doesn't mean body).
This Person, who existed from eternity, added to Himself a human body and human nature.
This Person never ceased being GOD, and now He will never cease being also man. He is now man in an exalted[glorified] form since the resurrection on the third day. He is also fully GOD and has always been fully GOD. He has never ceased being fully GOD.
