The average Bible-believing Christian today believes that we are living in the shadow of the Second Coming. Consequentially, they hold no long-range view of the future because they expect the Rapture to snatch them out of the world at any minute.
Postmillennialism, however, offers Christians an exciting hope-filled view of the future that encourages long-term planning and diligent labor for the glory of God. Postmillennialists believe that "the gospel is the power of God unto salvation" (Rom. 1:16) and that "the earth is the Lord's and the fulness thereof" (Psa. 24:1).
Thus, postmillennialists are committed to the world-conquering task that the Lord Jesus Christ gave his Church just before ascending to the right hand of God in heaven in the Great Commission. On the basis of these and many other Scriptures, postmillennialism offers an optimistic outlook on the future, urging Christians to believe that their labor is not in vain.
