In Christian eschatology (end-times theology), postmillennialism, or postmillenarianism, is an interpretation of chapter 20 of the Book of Revelation which sees Christ's second coming as occurring after (Latin post-) the "Millennium", a messianic age in which Christian ethics prosper. The term subsumes several similar views of the end times, and it stands in contrast to premillennialism and, to a lesser extent, amillennialism (see Summary of Christian eschatological differences).
Postmillennialism holds that Jesus Christ establishes his kingdom on Earth through his preaching and redemptive work in the first century and that he equips his church with the gospel, empowers the church by the Spirit, and charges the church with the Great Commission (Matt 28:19) to disciple all nations. Postmillennialism expects that eventually the vast majority of people living will be saved. Increasing gospel success will gradually produce a time in history prior to Christ's return in which faith, righteousness, peace, and prosperity will prevail in the affairs of men and of nations. After an extensive era of such conditions Jesus Christ will return visibly, bodily, and gloriously, to end history with the general resurrection and the final judgment after which the eternal order follows.
