Were you born of flesh?
Have you changed into a spirit being?
Do you remember how the Lord was able to stand before the disciples, suddenly materializing inside a stone building, behind locked doors? [John 20:19][Luke 24:36]
He had been "Born again"....resurrecting as a spirit. We will also..... at our resurrection....be born of the spirit [I Corinthians 15:50-52]. Notice again what He says to Nicodemus [John 3:3-8] 3 Jesus answered and said unto him, Verily, verily, I say unto thee, Except a man be born again, he cannot see the kingdom of God. 4 Nicodemus saith unto him, How can a man be born when he is old? can he enter the second time into his mother's womb, and be born? 5 Jesus answered, Verily, verily, I say unto thee, Except a man be born of water and of the Spirit, he cannot enter into the kingdom of God. 6 That which is born of the flesh is flesh; and that which is born of the Spirit is spirit. 7 Marvel not that I said unto thee, Ye must be born again. 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".
Our Lord was telling Nicodemus about a total change he would experience upon becoming "born again".....from flesh to spirit at the resurrection.
[1 Peter 1:3] Blessed be the God and Father of our Lord Jesus Christ, which according to his abundant mercy hath begotten us again unto a lively hope by the resurrection of Jesus Christ from the dead.
[1 Peter 1:21-23] Who by him do believe in God, that raised him up from the dead, and gave him glory; that your faith and hope might be in God. 22 Seeing ye have purified your souls in obeying the truth through the Spirit unto unfeigned love of the brethren, see that ye love one another with a pure heart fervently: 23 Being born again, not of corruptible seed, but of incorruptible, by the word of God, which liveth and abideth for ever.
[1 John 3:9] Whosoever is born of God doth not commit sin; for his seed remaineth in him: and he cannot sin, because he is born of God.
Do baptized, fleshly people sin? Yes, unfortunately, they still do.....as they have only been begotten of the spirit, not yet born of the spirit....born again of incorruptible seed.
Again, if you believe that Christ is a Divine person, then Christ being “born again/or Born from above” can not be reconciled to what you are saying, that is Christ needed to be born again. Now, if you are a Oneness pentecostal or Jehova’s Witness, then what you are saying is diamaterically opposed to orthodox Christian doctrine and in fact, is objectively not even Christianity.
