Just some thoughts for you:
We are created in the image of God who is tripartite (Father, Son, Holy Ghost).
We are tripartite beings.
1Th 5:23 And the very God of peace sanctify you wholly; and I pray God your whole spirit and soul and body be preserved blameless unto the coming of our Lord Jesus Christ.
We are given a new spirit when we are born again:
Eze 36:25 Then will I sprinkle clean water upon you, and ye shall be clean: from all your filthiness, and from all your idols, will I cleanse you.
Eze 36:26 A new heart also will I give you, and a new spirit will I put within you: and I will take away the stony heart out of your flesh, and I will give you an heart of flesh.
Eze 36:27 And I will put my spirit within you, and cause you to walk in my statutes, and ye shall keep my judgments, and do them.
Eze 11:19 And I will give them one heart, and I will put a new spirit within you; and I will take the stony heart out of their flesh, and will give them an heart of flesh:
Eze 11:20 That they may walk in my statutes, and keep mine ordinances, and do them: and they shall be my people, and I will be their God.
Joh 3:3 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.
Joh 3:4 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?
Joh 3:5 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.
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.
Absent from the body present with the Lord , our spirit man goes to God when we die:
2Co 5:6 Therefore we are always confident, knowing that, whilst we are at home in the body, we are absent from the Lord:
Ecc 12:7 Then shall the dust return to the earth as it was: and the spirit shall return unto God who gave it.
Jesus died for our sins and by faith in Him our souls are saved:
Heb 10:39 But we are not of them who draw back unto perdition; but of them that believe to the saving of the soul
Jesus came to die for our sins and by faith in Him our souls are saved (mind. will, intellect, emotions,etc).
We are given new bodies at His coming and it does not matter if we are physically alive or dead when He does:
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.
1Jn 3:2 Beloved, now are we the sons of God, and it doth not yet appear what we shall be: but we know that, when he shall appear, we shall be like him; for we shall see him as he is.
2Co 3:18 But we all, with open face beholding as in a glass the glory of the Lord, are changed into the same image from glory to glory, even as by the Spirit of the Lord.
