In Christian eschatology the rapture refers to the belief that either before, or simultaneously with, the Second Coming of Jesus Christ to earth, believers who have died will be raised and believers who are still alive and remain shall be caught up together with them (the resurrected dead believers) in the clouds to meet the Lord in the air. The concept has its basis in various interpretations of the biblical book of First Thessalonians and how it relates to interpretations of various other biblical passages, such as those from Second Thessalonians, Gospel of Matthew, First Corinthians and the Book of Revelation.
