Premillennialists fall into two primary categories: historic premillennialism and dispensational premillennialism. In general, Premillennialism is committed to the concept of an earthly reign by Jesus Christ of approximately a thousands years. Premillennialism sees Christ as physically present during this time and believes that Jesus Christ will return presonally and bodily to start the millennium.
Premillennialists agree that the world situation will be at its very worst just before Christ comes to establish the millennium.
The strength of this position is that there are no blibical passages with which premillennialism cannot cope or which it cannot adequately explain. In other words, there are passages from the Bible to give support on this position. The basis for this position is indeed solid.
