Since the 1840′s or so I think that most evangelical theologins have been postmillennialist.

“The postmillennialist believes that the millennium is an era (not necessarily a literal thousand years) during which Christ will reign over the earth, not from a literal and earthly throne, but through the gradual increase of the Gospel and its power to change lives. After this gradual Christianization of the world, Christ will return and immediately usher the church into their eternal state after judging the wicked. This is called postmillennialism because, by its view, Christ will return after the millennium.”

Even so Lord come quickly.
