Postmillennialism

A belief that Christ will return at the end of the millennium, a 1,000 year period, in which He has reigned through His church (Rev 20:4-6). This interpretation is considered faulty by most scholars and stands in contrast to the generally accepted pre-millennial view that Christ’s second coming will occur after the rapture and tribulation yet prior to His 1000 year reign.
