How can it be a process which keeps going and going if we can NOT BE BORN AGAIN until we fully repent?
One question at a time because I tend to be verbose. What and when is born again?
Joh 3:6 That which is born of the flesh is flesh; and that which is born of the Spirit is spirit.
Joh 3:7 Marvel not that I said unto thee, Ye must be born again.
Joh 3:8 The wind bloweth where it listeth, and thou hearest the sound thereof, but canst not tell whence it cometh, and whither it goeth: so is every one that is born of the Spirit.
This passage says a lot...
Born of the flesh, we all are. Born of the spirit is spirit. Only One has been born of spirit thus far. This is not speaking of some spiritual experience, this is speaking of birth by resurrection. Notice the description in verse 8. Humans don't fit that description, we are not invisible and only known by the effects of what we do. We are not born yet...
1Co 15:22 For as in Adam all die, even so in Christ shall all be made alive.
1Co 15:23 But every man in his own order: Christ the firstfruits; afterward
they that are Christ's at his coming.
1Co 15:35 But some man will say, How are the dead raised up? and with what body do they come?
1Co 15:36 Thou fool, that which thou sowest is not quickened, except it die:
The dead are not raised until the return of Christ at the resurrection. Until then, they are dead.
1Co 15:37 And that which thou sowest, thou sowest not that body that shall be, but bare grain, it may chance of wheat, or of some other grain:
1Co 15:38 But God giveth it a body as it hath pleased him, and to every seed his own body.
God gives us a spirit body at the resurrection, until then we are flesh.
1Co 15:39 All flesh is not the same flesh: but there is one kind of flesh of men, another flesh of beasts, another of fishes, and another of birds.
1Co 15:40 There are also celestial bodies, and bodies terrestrial: but the glory of the celestial is one, and the glory of the terrestrial is another.
Paul is using flesh here and celestial bodies here to show that there are different degrees. There is God, the twenty-four elders, there are Cherubim, Seraphim, angels, the Devil, demons and perhaps other spirit beings we do not yet know about.
1Co 15:41 There is one glory of the sun, and another glory of the moon, and another glory of the stars: for one star differeth from another star in glory.
There are levels or ranks.
1Co 15:42 So also is the resurrection of the dead. It is sown in corruption; it is raised in incorruption:
1Co 15:43 It is sown in dishonour; it is raised in glory: it is sown in weakness; it is raised in power:
1Co 15:44 It is sown a natural body; it is raised a spiritual body. There is a natural body, and there is a spiritual body.
What is the difference? We become spirit at the resurrection.
1Co 15:45 And so it is written, The first man Adam was made a living soul; the last Adam was made a quickening spirit.
1Co 15:46 Howbeit that was not first which is spiritual, but that which is natural; and afterward that which is spiritual.
1Co 15:47 The first man is of the earth, earthy: the second man is the Lord from heaven.
1Co 15:48 As is the earthy, such are they also that are earthy: and as is the heavenly, such are they also that are heavenly.
1Co 15:49 And as we have borne the image of the earthy, we
shall also bear the image of the heavenly.
Note the tense here, "we shall also bear" is future tense.
1Co 15:50 Now this I say, brethren, that flesh and blood cannot inherit the kingdom of God; neither doth corruption inherit incorruption.
1Co 15:51 Behold, I shew you a mystery; We shall not all sleep, but we shall all be changed,
We shall all be, again future tense. When?
1Co 15:52 In a moment, in the twinkling of an eye,
at the last trump: for the trumpet shall sound, and the dead shall be raised incorruptible, and we shall be changed.
1Co 15:53 For this corruptible must put on incorruption, and this mortal must put on immortality.
1Co 15:54 So when this corruptible shall have put on incorruption, and this mortal shall have put on immortality, then shall be brought to pass the saying that is written, Death is swallowed up in victory.
1Co 15:55 O death, where is thy sting? O grave, where is thy victory?
When do we obtain immortality? At the Last Trump at Christ's return. Paul did not consider himself to have obtained...
Php 3:10 That I may know him, and the power of his resurrection, and the fellowship of his sufferings, being made conformable unto his death;
Php 3:11 If by any means I might attain unto the resurrection of the dead.
Php 3:12 Not as though I had already attained, either were already perfect: but I follow after, if that I may apprehend that for which also I am apprehended of Christ Jesus.
Php 3:13 Brethren, I count not myself to have apprehended: but this one thing I do, forgetting those things which are behind, and reaching forth unto those things which are before,
Php 3:14 I press toward the mark for the prize of the high calling of God in Christ Jesus.
He did not consider himself to have made it yet, not until the resurrection.
