PLEASE STATE THE VERSE THAT SAYS SPIRIT MEANS IMMORTAL.
Gen 2:7 And the LORD God formed man of the dust of the ground, and breathed into his nostrils the breath of life; and man became a living soul.
Doesn't say he became an immortal soul. The breath of life goes back to God who gave---and man becomes dust again.
It might help you a lot if you understand that that there is either life or death-there is either breathing or not breathing, there is either immortality or mortal.
You completely ignore scripture.
Rom_2:7 To them who by patient continuance in well doing seek for glory and honour and immortality, eternal life:
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.
1Ti 6:15 Which in his times he shall shew, who is the blessed and only Potentate, the King of kings, and Lord of lords;
1Ti_6:16 Who only hath immortality, dwelling in the light which no man can approach unto; whom no man hath seen, nor can see: to whom be honour and power everlasting. Amen.
2Ti_1:10 But is now made manifest by the appearing of our Saviour Jesus Christ, who hath abolished death, and hath brought life and immortality to light through the gospel:
1Ti_1:17 Now unto the King eternal, immortal, invisible, the only wise God, be honour and glory for ever and ever. Amen.
and you completely ignored these
Gen 3:22 And the LORD God said, Behold, the man is become as one of us, to know good and evil: and now, lest he put forth his hand, and take also of the tree of life, and eat, and live for ever:
Rev_2:7 He that hath an ear, let him hear what the Spirit saith unto the churches; To him that overcometh will I give to eat of the tree of life, which is in the midst of the paradise of God.
Rev_22:2 In the midst of the street of it, and on either side of the river, was there the tree of life, which bare twelve manner of fruits, and yielded her fruit every month: and the leaves of the tree were for the healing of the nations.
Rev_22:14 Blessed are they that do his commandments, that they may have right to the tree of life, and may enter in through the gates into the city.
It can't get any clearer. We are not immortal, we are given immortality. Adam and Eve were not given immortality---they had to eat of the tree of life for that and we will have that tree of life also.
