Gary North, in "Millennialism and Social Theory" (p.136-137), demonstrates the worldly outlook of the Christian Reconstructionists. He labels those who disagree with his postmillennial doctrine as "pessimillenialists." That is, they are pessimistic because they do not believe that Christians will conquer the world before the physical return of Christ. One of the greatest faults he sees in premillenialists is their conviction that Christians should be looking for the return of Jesus Christ. According to him: "Christians were told to look skyward prior to the fall of Jerusalem... But their deliverance came in history... That one-time deliverance of the early Church is today long behind us. It is surely time for Christians to begin lookingforward, in time and on earth, for their deliverance, not upward." He even scolds an amillennialist for saying, "Come, Lord Jesus, come."
It evidently means nothing to North that this statement is only a variation of "Even so, come, Lord Jesus," which is found at the end of the book of Revelation (Revelation 22:20). And Revelation was written around 95AD -- 25 years after the destruction of Jerusalem. Unfortunately, many who reject much of the teaching of the Reconstructionists are buying into the idea of looking for deliverance on the earth and not from above. This rejection of the soon return of Christ actually indicates the closeness of Christ's return: "Be ye therefore ready also: for the Son of man cometh at an hour when ye think not" (Luke 12:40). Besides, what could be more optimistic than to know that at any moment Jesus could come and we will forever be with Him? That is pessimistic only if your hope is in this world and not in Jesus Christ.
