Rapture of the Saints

Many ask is the word rapture in the Bible? Is it escape theology? When will it happen? I believe in the Rapture of the Church and I also believe it is before the Tribulation period begins. I am Pre-Trib. But I also will not argue the point. 1 Thessalonians 4:13-18 is the definitive scripture. Live in the Word! & Walk in His Spirit!
