OMG !!...are you talking about the Bible or some weird science-fiction movie?
Where on earth are you getting this stuff?
Gen 2:7:
"And Jehovah God went on to form the man out of dust from the ground and to blow into his nostrils the breath of life, and the man became a living person."
What does it say? Jehovah formed the man from the dust (elements) of the earth, and when God animated him with the "breath of life" he
became "a living person." (Heb nephesh "soul")
The Bible's formula is simple. A body + spirit (breath) = a soul. There is no incarnation....no reincarnation, no putting of souls into bodies. The "soul" is the person themselves, not something that inhabits the body. The "spirit" is not the soul but the breath that keeps us alive. When the last breath leaves our body, the soul dies. All consciousness ceases. (Ezek 18:4; Psalm 146:4; Eccl 9:5, 10) The meaning of the word "soul" in Hebrew is a "breather". Animals are souls too.
Rev 22:1-5:
"And he showed me a river of water of life, clear as crystal, flowing out from the throne of God and of the Lamb 2 down the middle of its main street. On both sides of the river were trees of life producing 12 crops of fruit, yielding their fruit each month. And the leaves of the trees were for the healing of the nations. 3 And there will no longer be any curse. But the throne of God and of the Lamb will be in the city, and his slaves will offer him sacred service; 4 and they will see his face, and his name will be on their foreheads. 5 Also, night will be no more, and they have no need of lamplight or sunlight, for Jehovah God will shed light upon them, and they will rule as kings forever and ever."
Remember this was a vision. The things John is shown are symbolic, not literal. This foreshadows the results of God's kingdom rulership in the hands of his Christ and those chosen from the earth to rule with him. Those who inhabit the heavenly realm have no need of the things that sustain earthly creatures, like sunlight.
Rev 20:6 tells us that those who will rule with Jesus are also priests as well as kings. These will bring the blessings of the kingdom to all obedient ones, curing their illnesses, eliminating death, and restoring God's rule over mankind. (Rev 21:1-5)
Can you tell me who it is that these ones will rule?...and for whom they will act as priests? Those who go to heaven give up their sinful flesh and are given divine spirit bodies so that they can dwell in the presence of God. These are no longer sinners so for who do they perform their duties as priests?
