The person who has received God's gracious gift of eternal life has already been judged at the cross, and all of his/her sin debt paid for by the currency of the Blood of Jesus that was shed there, and completely forgiven and mercifully forgotten. That is why I used the word "existence" and not in this context "body."
Yet, understanding from the whole context of Scripture regarding soteriology as it ties in with eschatology, Several things are happening in the transaction that takes place at the moment a new entity is begotten in the spiritual realm by the fruition of God's generative seed (1 John 3:9), which is the Spoken Word of God (Rom. 10:17).
However, though or fleshly bodies still exist in this realm, its "old (hu)man" has died. Both the new spiritual entity and one's soul (completely changed by its new point of view, Isaiah 1:18) still exist in the old husk, as well as the Spirit of God Who is now welcomed as a loving, disciplining guide of both thinking and actions arising from one's beliefs.
This new spiritual integral constituent of the new person (2 Cor. 5:17) bridges the two realms, being both in the temporal worldly realm, water-baptized into a local imperfect fallible assembly of humans professing allegiance to Christ and also in the timeless heavenly spiritual realm at once, having been spiritually baptized into the perfect infallible Church of The First-Born Son of God as one of is members of whom Jesus is their Lord and Master according to each having freely chosen to enlist as a permanent member of His Army f Saints.
From the temporal aspect, the redeemed risen recruit that still exits in the fleshly body cannot simultaneously possess a spiritual body. Physical death is the withdrawal of the human's continuing rational soul and spirit away from the now non-functioning flesh machine, with that person transitioning either to Hades or Paradise (Lk. 16:19-26), being sentient but without the spiritual body promised to come later. Presence in the spiritual realm does not necessarily imply absence of a personality in the temporal dimension.
In answer to your question, what I am proposing is that spiritual birth is permanent, and that portion of the new being that invests the physical body is one with the portion that exists in the Paradise of heave, assembling with other such entities as the Church of the First-Born told of in Hebrews 12:22-24, which only currently exists only in Heaven in the Kingdom of God/Christ and nowhere else.
While on earth and still in a human body, the truly saved person has the temporal use of it to further God's interests in this realm as long as He desires. When the body gives out, or the person can no longer have an effect temporally, I believe He withdraws on out of the body and out of the udens of the natural realm, to have fellowship with Him and other kindred spirits, without a spiritual body until the fullness of time, whence all those of which The Bride and the Friends of the Bride will be instantly be clothed with a new humanoid body (1 John 3:1-2).
What I say is that what I said about Davy and Natalie Lloyd in Post #134 is true, that the sill exist as before in therms of soulish personality-limited qualities that define each, yet now without a body (Colossians 3:1-3), have a future of accompanying Jesus wherever He goes (1 Thess. 4:12-5:2, Col. 3:4), no longer burdened with the groans of progressive sanctification (Col. 3:5; Rom. 8:18-23,36-39), and fit for unalloyed service to the Prince of Peace, the King of Kings (1 Cor. 6:2-3, Rev. 20:6).
Look to it, my FRiend!
Which in no way cancels out the GWT judgement that is coming.
Scripture disagrees with the claim, accepted by millions, that believers are in heaven RIGHT NOW.
1 Thessalonians 4:16-17 King James Version (KJV)
16 For the Lord himself shall descend from heaven with a shout, with the voice of the archangel, and with the trump of God: and the dead in Christ shall rise first:
17 Then we which are alive and remain shall be caught up together with them in the clouds, to meet the Lord in the air: and so shall we ever be with the Lord.
