The elder of Revelation 7:13 identifies the great multitude as “the ones who come out of the great tribulation.” I believe the greatest period of revival that the world has ever known will take place immediately after the Rapture.
There will be so many people who have been out on the fringes, those who have heard the gospel but who haven’t responded to it by committing their lives to Jesus Christ. Their loved ones who have been witnessing to them for a long time will suddenly disappear. I believe this will bring many to their knees, crying out to Jesus for salvation. Pastor Chuck Smith
