I actually agree with this statement, none of us are immortal quite yet.
Mark 10:30; but that he will receive a hundred times as much now in the present age, houses and brothers and sisters and mothers and children and farms, along with persecutions; and in the age to come, eternal life.
Luke 18:30; who will not receive many times as much at this time and in the age to come, eternal life."
Luke 20:35; but those who are considered worthy to attain to that age and the resurrection from the dead, neither marry nor are given in marriage;
Luke 20:36; for they cannot even die anymore, because they are like angels, and are sons of God, being sons of the resurrection.
No humans have ascended to heaven, not yet.. ( there could be a few notable exceptions, Elijah, Enoch, Jesus )
Prov 30:4; Who has ascended into heaven and descended? Who has gathered the wind in His fists? Who has wrapped the waters in His garment? Who has established all the ends of the earth? What is His name or His son's name? Surely you know!
John 3:13; "No one has ascended into heaven, but He who descended from heaven: the Son of Man.
Acts 2:34; "For it was not David who ascended into heaven, but he himself says: 'THE LORD SAID TO MY LORD, "SIT AT MY RIGHT HAND,
Yes, I am familiar with this verse.
2Cor 5:8; we are of good courage, I say, and prefer rather to be absent from the body and to be at home with the Lord.
It seems to conflict with the verses above, but the obvious answer to reconcile these is... when are we absent from the body?
1Tim 6:16; who alone possesses immortality and dwells in unapproachable light, whom no man has seen or can see. To Him be honor and eternal dominion! Amen.
Right now, only Jesus has eternal life.... however that will change in the future. Right now, no one has ascended to heaven nor can see Jesus there.
1 Cor. 15:53-54
"For this corruptible must put on incorruption, and this mortal must put on immortality.
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."
It's the physical body that's not yet immortal. That takes place at the resurrection, then and only then is our salvation completed.
The soul and spirit of man is not subject to physical death, it's not mortal, therefore it's immortal.
Christ said, don't fear those who can kill the body but cannot kill the soul, fear Him who can destroy both body and soul in hell.
The word "destroy" in this verse is not inhalation, we can plainly see in Scripture they are punished for eternity.
