One day, our mortality will be instantly transformed to immortality
Behold, I tell you a mystery. We will not all sleep, but we will 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 will be changed. For this perishable body must become imperishable, and this mortal must put on immortality.
