Behold, I tell 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 trumpet. For the trumpet will sound, and the dead will be raised incorruptible, and we shall be changed.
These verses describe the same event we read about yesterday in 1 Thessalonians 4:16-17 . Paul again mentions the trumpet, this time calling it the “last trumpet,” which corresponds to the seventh trumpet of Revelation 11:15 .
This change from corruptible human flesh to spiritual life is a wonderful mystery and the hope of Christians.
Revelation 20:6 calls this resurrection to immortality the “first resurrection.” To call it the first is to imply it is not the only one. To learn more about what the Bible teaches about resurrections, read “Resurrections: What Are They?”
