The same message of the Rapture of the
Church, is also in Paul's letter to the
Corinthians. He said,

"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,"
1 Corinthians 15:51-52
