Rapture , resurrection ....the same event.
1 Corinthians 15:52
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.
Dead people are "resurrected".....those that are alive and remain will be "raptured".
1 Thessalonians 4:17
Then we which are alive and remain shall be caught up together with them in the clouds, to meet the Lord in the air: and so shall we ever be with the Lord.
