By the sweat of your brow you will eat your food until you return to the ground, since from it you were taken; for dust you are and to dust you will return. (Genesis 3:19, NIV)
Just as people are destined to die once, and after that to face judgment. (Hebrews 9:27, NIV)
From these verses, we can deduce that "All must die once (or at least once) and return to dust".
For the Lord himself will come down from heaven, with a loud command, with the voice of the archangel and with the trumpet call of God, and the dead in Christ will rise first. After that, we who are still alive and are left will be caught up together with them in the clouds to meet the Lord in the air. And so we will be with the Lord forever. (1 Thessalonians 4:16-17)
Listen, I tell you a mystery: We will not all sleep, but we will all be changed— in a flash, in the twinkling of an eye, at the last trumpet. For the trumpet will sound, the dead will be raised imperishable, and we will be changed. For the perishable must clothe itself with the imperishable, and the mortal with immortality. (1 Corinthians 15:51-53, NIV)
These verses are very important basis for Christian eschatology belief called Rapture. As per these verses, on the the day of Rapture, first, the dead who belonged to Christ will be resurrected and they will be transformed, second, those who are alive and believe in Christ will be caught up, who may or may not be transformed.
What I cannot understand is that if all are destined to die, then it is a contradiction that believers will be caught up alive, without ever facing death. Though Enoch and Elijah were taken alive, some believe that they are the two witnesses mentioned in
Revelation 11, who will be killed by the Beast, thus still fulfilling the words of God that all must die.
Is there any possibility (apart from the scripture about Rapture), that some people will never face death?
Does God's word "Dust to dust" leave any exception?
How do theologians explain this contradiction?
