1 Corinthians 15:51

Paul announces a revealed truth he calls a "mystery" -- not something puzzling, but something once hidden and now made known. The truth is this: "We shall not all sleep, but we shall all be changed." "Sleep" is Paul's gentle word for death. He reveals that not every believer will have died before the Lord returns; some will still be living. But whether living or dead, all will be transformed.

The emphasis falls on that universal change. The present body, mortal and perishable, is not suited for the life to come. So at the last, all who belong to Christ will be changed -- given new, imperishable bodies fit for resurrection life. Those who have died will be raised, and those still alive will be transformed without passing through death. Either way, transformation is certain and necessary. This was a comforting and clarifying word for the Corinthians, some of whom doubted the resurrection altogether. Paul assures them that God's plan embraces both the living and the dead, and that the destiny of believers is not a disembodied existence but a glorious transformation of the whole person. The word "Behold" signals the wonder of it: a change so complete and so good that it can only be received as revelation. The believer's future is not loss but transformation into something far greater.
