The Rapture is a rescue, before God begins to pour out His wrath on the unbelievers in ever increasing severity. Folks will be surprised with whom will be snatched away ... think ‘the innocent’, etc. If you are among the redeemed, you already have a reward for it is God Who is abiding in your before dead spirit now come alive forever more. His presence in you is the resonance point for your sudden transformation, physically, to a new creation in a spacetime coordinate system which exists and is no further from you now than the length of your forearm.
1’st Corinthians 15:51-56
