Postmillenialism is the belief that Christ, with His coming, His atonement, and His continuing regenerative power in those whom He calls, creates in His redeemed people a force for the reconquest of all things. The dominion that Adam first received and then lost by his fall will be restored to redeemed man. God’s people will then have a long reign over the entire earth, after which, when all enemies have been put under Christ’s feet, the end shall come, and the last enemy, death, will be destroyed.

 Postmillennialism is an interpretation of Revelation chapter 20 which sees Christ’s second coming as occurring after the “millennium,” a golden age or era of Christian prosperity and dominance. The term includes several similar views of the end times, and it stands in contrast to premillennialism (the view that Christ’s second coming will occur prior to His millennial kingdom and that the millennial kingdom is a literal 1000-year reign) and, to a lesser extent, amillennialism (no literal millennium).
Postmillennialism is the belief that Christ returns after a period of time, but not necessarily a literal 1000 years. Those who hold this view do not interpret unfulfilled prophecy using a normal, literal method. They believe that Revelation 20:4-6 should not be taken literally. They believe that “1000 years” simply means “a long period of time.” Furthermore, the prefix “post-” in “postmillennialism” denotes the view that Christ will return after Christians (not Christ Himself) have established the kingdom on this earth.
Those who hold to postmillennialism believe that this world will become better and better—all evidence to the contrary notwithstanding—with the entire world eventually becoming “Christianized.” After this happens, Christ will return. However, this is not the view of the world in the end times that Scripture presents. From the book of Revelation, it is easy to see that the world will be a terrible place during that future time. Also, in 2 Timothy 3:1-7, Paul describes the last days as “terrible times.”
