THE RAPTURE
Note: Throughout this I shall "paraphrase" scripture for simplicity. I will place a (Pp:) in front each time I do. I will also include the scripture reference for you to look up.
The "Rapture" is when Jesus comes back to the earth to take the believers to heaven with Him, but he doesn't touch-down (so to speak). He shall descend from the heavens and shout for us to rise to Him. In that moment we shall be transformed from our earthly (flesh) bodies into our heavenly (spirit) bodies. We will rise to meet Him in the air, walls and roofs will not stop us, we shall pass right through them. This is different from His second coming because only the believers will see Him and he will not land.
