Listen I will tell you a mystery

" Listen I will tell you a mystery! We will not all die, but will all be changed - in flash, in a moment, in the twinkling of an eye, and the last trumpet. For the trumpet will sound, and the dead will be raised imperishable and we will be changed. For this perishable body must put on imperishability,  and this mortal body must out on immorality, then the saying that is written will be fulfilled:
"Death has been swallowed up in
victory."
Where , O death is your victory?
Where O death is your sting?
The sting of death is sin, and the
power of sin is the law. But thanks be to God,
who gives us the victory through our Lord Jesus Christ.
Therefore, my beloved be steadfast, immovable, always excelling in the work of the Lord, because you know that in the Lord your labor is not in vain."

I Corinthians 15:51 - 58 (New Revised Standard Version)
