Food for Thought

"If the rapture had occurred in the first century preceding the tribulation which the book of Revelation describes, they were assured of deliverance. By contrast, those sealed out of the twelve tribes of Israel in 7:4 clearly go through the time of trouble. This implies the rapture of the church before the time of trouble referred to as the great tribulation. Such a promise of deliverance to them would seemingly have been impossible if the rapture of the church were delayed until the end of the tribulation prior to the second coming of Christ and the establishment of the kingdom."
