So does that mean that He didn't send His son, that he sent the other God and pretend He is His Son or sent part of Himself. Wouldn't that mean that God lied? Because He didn't send us his son.
Imagine a being with three parts. Even something like air it is all at once. Sometimes we can not fully perceive the actual being as we are limited by the thoughts of the flesh.
These are things I was told but for me I think they might be three different things. After all in revelations Jesus is standing beside god. Though again that is the limitation of our capability to understand anything else so it could be the best way God had to depict what is going on in the future.
