The pre-Trib Rapture is the event in which Christ returns to the earth but stays in the air and on a cloud. He will return to remove all His saints/overcomers from the earth. The Second Coming (the Second Advent) is the event in which Christ returns to the earth (with the clouds – with His Host of raptured saints/the armies of Heaven). He will return to bring the Tribulation Period to an end by defeating the Antichrist and his evil world empire in the Battle of Armageddon.
Clearly understanding the hidden Divine Truth that pertains to the “Rapture” is possible only for those believers who are full of the Holy Spirit and who are accepting His leading and teaching. To the nonbelievers and to those doubting and skeptical believers who are not full of the Holy spirit and therefore who are not always led or taught by Him, the “Rapture’s” unambiguous understanding will remain controversial—will remain a mystery—so that they will never be in agreement with the Bride of Christ.
