Dispensationalism is a new way of viewing Scripture, originating in the early 1800′s, popularized by J.N. Darby and C.I. Schofield, and continues to be popular through the writings of Hal Lindsey, etc. But a vision of victory in history is taught from Genesis to Revelation; a victory which Christ’s people not only are given (by the “it is finished” of the Cross), but in which they also participate as in “The God of Peace will soon crush Satan under your feet” (Romans 16:20). We follow Him who goes forth conquering His enemies (Rev. 19:11-14) until all His enemies are subdued (Heb. 10:12-13; Psalm 110:1; Rom. 16:20), and the final enemy, death, conquered (legally and effectively at the Cross by Christ “the firstfruits”) but not fully subdued until the “rapture”, the resurrection (conquered for all of God’s people – 1 Cor. 15:24-27, on the last day when no more days of earth history follow (John 6:39-40).
Let your heart hold to all the hope and delight the Lord has given. I believe the Book of Revelation is about the New Jerusalem in contrast to the Old Jerusalem, Babylon, Sodom, “where also their Lord was crucified” (Rev. 11:8). It is the removal of the Old Jerusalem that had killed the prophets and the Lord Jesus (1 Thess. 2:15; Luke 13:34-35; Rev. 1:7).
I mention William Carey and how God used him to initiate the modern missionary movement to point out that Carey was a postmillennialist. In other words Carey’s faith, vision and courage that led him to India was founded upon a vision of the future that anticipated the discipling of the nations and victory for the Gospel in history before Jesus comes back or the rapture happens.
