There is a generation of Christians living
today who will not die. They will be caught
up in their bodies, to be in the presence of
Jesus. Paul speaks of it in 1 Corinthians 15

"Behold, I show you a mystery: We shall
not all sleep, but we shall all be changed, 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," (vs 51 & 52)
