That is true but which is not at all contrary to our position on Jn. 3:3, as this does not say one who is born from above as a child of God, in which God sends the Spirit of His Son into the believer crying "Abba, Father," (Gal. 4:6) and is a "new creation," (2Cor. 5:17) means that such no longer has a body of flesh and blood, and is in the literal manifestation of the kingdom of God, though he is now spiritually in that kingdom. (Col. 1:13)
Therefore they do not wage the war of faith after the flesh. (Jn. 18:36; 2Cor. 10:3,4; Eph. 6:13)
But it teaches that one must be born of the word of truth of the gospel, (Ja. 1:18) in order to see that literal manifestation, and the indwelling Spirit is a pledge of that. ( Eph. 1:13; 1 Peter 1:3)
To God be the glory.
I have no desire to diminish you, but your position WRT our bodies is in total conflict with the scriptures.
Our bodies must change because this physical world is to be destroyed, and we need a body that can live in the realm of God. Paul made this abundantly clear in 1Cor 15, as did Yeshua in his very technical discussion with Nicodemus.
Paul made it clear also that this change cannot be made until the last trump, when Yeshua shows up in the cloud with his angels to gather his elect. Obviously those that have pre-deceased us no longer have Earthly flesh and blood bodies anyway, so the need for the incorruptible body is to be understood.
None of this has anything to do with the indwelling of the comforter; it is simply a life issue for our future dwelling place.
