If anyone has a problem with anything I have posited below please give me the opportunity to clear it up especially if rewording it will make the difference. I don't want anyone going away confused because I didn't word something correctly. Thank you.
A man's soul and body are held together by the "Breath of Life" that is of God which we commonly call the "spirit of man” or our “human spirit", our human spirit being loan from God for as long as his body remains alive, intact with his “mind, will and emotions”, his soul, that which makes man, eternal:
"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". Genesis 2:7 (KJV)
Man's being consists of body and soul and spirit. Separate them and he stops living on this earth.
For the new born from above, it is the same Spirit and for which Paul has these words: "Have this mind in yourselves, which is yours by Christ Jesus, who, though he was in the form of God, did not count equality with God a thing to be grasped", Philippians 2:5-6 (CRV). This is also why Jesus could say this about Himself because His human spirit was in complete union with the Spirit of God: "The glory that you have given me I have given to them, that their [souls] may be one even as we are one [soul]", John 17:22 (ESV). No death in that even when the body decays because the soul departs unto God having been reconciled to Him and his human spirit is already of the "source of life" making the two, one, to await the resurrection of the body.. It cannot be otherwise.
To sum up we can use the words of Jesus to do so:
". . . . I am the resurrection, and the life: he that believes in me, though he were [physically] dead, yet shall he live: And whosoever lives and believes in me shall never die. .. . . " John 11:25-26 (KJV) His soul, [mind, will and emotions] and spirit are in His keeping: And . . "if the Spirit of him [God’s, "breath of life"] that raised up Jesus from the grave dwells in you, He that raised up Christ from the dead shall also quicken your mortal bodies by His Spirit that dwells in you." Romans 8:11 (KJV)
Hence, the soul, that which a person is, cannot return to God without being reconciled to Him; without the peace made in man’s behalf by Jesus Christ is “fully” received to his soul.. . . with the stamp of God on it.
