Oh wait a minute, DUH....
You are saying that God has a dead person's breath/life somewhere. He will bring that back with Him when He raises the dead and the living?
I am going to answer you and onelove at the same time.
Genesis 2:7 And the LORD God formed man of the dust of the ground, and breathed into his nostrils the breath of life; and man became a living soul. Breath = living soul
Matthew 10:28 And fear not them which kill the body, but are not able to kill the soul: but rather fear him which is able to destroy both soul and body in hell.
Can not kill the soul for that is the very breath that goes back to God when we die. Our soul can never die and is preserved until Gods final judgment at the end of time. It is that breath of God brethed into us that made a living soul. Breath = living soul.
No one has ever entered the third Heaven where God sits on His throne. Third Heaven is where God and the holy angels and spirits (souls) of just men dwell. It is called “The heaven of heavens,” Deuteronomy 10:14; 1 Kings 8:27; Psalms 115:16; 148:4; 1Kings 8:27; Psalms 2:4.
Ecclesiastes 12:7 Then shall the dust return to the earth as it was: and the spirit (soul) shall return unto God who gave it.
Ruach, the Hebrew word for spirit here, means "breath" or "wind" as well as "spirit".
1John 3:2 Beloved, now are we the sons of God, and it doth not yet appear what we shall be: but we know that, when he shall appear, we shall be like him; for we shall see him as he is.
Act 1:11 Which also said, Ye men of Galilee, why stand ye gazing up into heaven? this same Jesus, which is taken up from you into heaven, shall so come in like manner as ye have seen him go into heaven.
Luke 24:33-53 We see that Jesus had flesh and bone and did eat with the Disciples, but now the flesh was glorified. Just as we will see Jesus the way he desended into Heaven is the same way we to will be resurrected from the grave if we are not alive when Christ returns which gives the saying in 1Corinthians 15:55 it's meaning. This body will have put on immortality and become an incorruptable body that also eats and drinks being flesh and bone, but now being a sinless glorified body given by the Father.
1Corinthians 15 we are resurrected into a Spiritual body that scripture does not give detail what it will look like, but will be like that of Christ glorified body that eats and drinks as when he came and showed himself to the Disciples he told them to touch him and also sat and ate with them.
