Luke 21:36 36 Watch therefore, and pray always that you may be counted worthy to escape all these things that will come to pass, and to stand before the Son of Man."
The "catching up" IS the rapture! The rapture is not the same event as the return of Jesus to earth.
Listen, I tell you a mystery: We will not all sleep, but we will all be changed— 52 in a flash, in the twinkling of an eye, at the last trumpet.(raptured=caught up) For the trumpet will sound, the dead will be raised imperishable, and we will be changed. 53 For the perishable must clothe itself with the imperishable, and the mortal with immortality. 54 When the perishable has been clothed with the imperishable, and the mortal with immortality, then the saying that is written will come true: “Death has been swallowed up in victory.” 1Corinthians 15:51-54
