Whoa there.....lets back up a little....
Can I ask you what
"the spirits of all mankind who have ever been" are, according to your belief?
The spirit in man is not the same as spirit beings who inhabit the heavenly realm. Man's spirit is the spark of life that is sustained with every breath, keeping the physical organism alive. We have a spiritual side to our nature, because, out of all the creatures on this planet, we alone feel the need to worship our Creator.....but we are mortal humans who were designed to live as material beings forever on earth. This life was not supposed to be a training ground for heaven.
"Jesus is a spirit son of God, just like us"? We are fleshly sons and daughters of God, not "spirit sons". Jesus was "only begotten" long before he was sent into the world to become the Christ. (1 John 4:7-10) The pre-human Jesus was the Word (Logos, spokesman) who was "with God" before all other things were brought into existence. (Col 1:15, 16) He is not God nor is he a part of God. He is "the son of God".
There is no "godhead"...there is "one God, the Father and one Lord Jesus Christ" (1 Cor 8:5, 6; John 17:3)
Firstly, there is one God, not three. The Jews were monotheists who did not ever worship a triune God....and Jesus was Jewish. He did not once claim equality with his God, but rather directed all worship to the Father "alone" (Luke 4:8)
There is no "Holy Ghost". There is holy spirit, which is not a person. "Ghost" was a German word (geist, meaning spirit) adopted by trinitarians in an attempt to make God's spirit part of a threesome. The Bible never does.
Huh??
Where did you get that idea? "God is a spirit" (John 4:24) not a being of flesh. Flesh and blood cannot exist in the spirit realm. This is why the ones taken to heaven to rule with Christ need to leave their mortal bodies of flesh behind and be transformed into spirit creatures in order to dwell in the presence of God. (1 Cor 15:50-57)
My goodness....only one part of God doesn't have a body? Really?
Where did you come across these beliefs? I have never heard of this before.
Ah......LDS by any chance?
Sorry, but the Bible does not even hint at such an idea.
