What is the mystery Paul reveals in 1 Corinthians 15:51?
The mystery Paul reveals in 1 Corinthians 15:51 is the rapture: a group of believers will not die physically but will all be changed. This truth was never revealed in Scripture before, had no hint in the Old Testament, and Jesus never referred to it. They will not go to heaven in the old body.
Les teaches that 1 Corinthians 15:51 is a glorious one. He says Paul writes, 'Behold, I show you a secret,' a truth never before revealed in Scripture. There is no hint of it in the Old Testament, and Jesus never referred to it. Les identifies this secret as the rapture, though it is not called that in the text. The secret is that a group of believers will not die physically; instead, they will all be changed. As Les puts it, we are not going to go up to heaven in this old body.
Behold, I shew you a mystery; We shall not all sleep, but we shall all be changed,
