Since the rise of Scofieldism in the last hundred years or so there has been an increasingly pessimistic outlook on the culmination of history. It seems that the dominant eschatological view today is equivalent to that of a house that is being torn down. Once this demolition of earth is complete (there is also some sort of secret “rapture” mixed in here somewhere, where the Church is lifted out of the decaying earth, because, lets face it, if you’re inventing an eschatology with all these bad things happening, you better write yourself out of it), Jesus will come thundering back.
Is this what the Bible teaches? Does Scripture show that God’s world will suffer incredible defeat before the return of Christ? I intended to promote a view here that answers emphatically: “Nah son!”
Although not as prevalent in today’s evangelical world as it was the evangelical world of yesteryear, there is a view of the consummation of all things that’s is explicitly optimistic. This eschatology of victory is known as postmillennialism.
Simply put, things will get better. The gospel will achieve its full victory as the Great Commission is fulfilled and a majority of the world is converted. The prophet Isaiah says that there will be a day where “the earth shall be full of the knowledge of the LORD, as the waters cover the sea (Isa. 11:9). God did not set up the earth only for it to go down in flames. Jesus is not sitting at the right hand of the Father watching things get worse. Jesus has been promised that he will reign until all things are made subject to him (Ps. 110:1; Heb. 10:13, Matt. 23:44). This will not happen by things being beaten to a pulp.
A common objection against Jesus’ victory in history is that the world does not appear to be getting any better. This is a result of “newspaper exegesis.” Christians must look at the Bible as their authority on what will happen during the “end times,” not modern media. As displayed a little above, this view is not without Scriptural warrant. God’s plan is to put all things subject to Christ, as the knowledge of the Lord covers the earth. This is not just silly optimism; these are ideas set forth in the Holy Writ.
The question then arises: What will this time of increasing gospel prosperity look like? Noted postmillennial scholar Dr. Kenneth L. Gentry answers:
“It will be a great time of domination of Christianity, not in an oppressive sense, but in a gracious sense that the world, education, politics, news media, and everything else will be working and operating on the basis of Christian principle. So the postmillennialist is considered to be an optimist. He views history as ultimately issuing forth in a time of great Gospel prosperity and blessing.” 
This post is not intended to be an exhaustive, exegetical defense of postmillennialism. This is merely to show that there is an alternative to the extremely pessimistic outlook of the common premillennial view. We can have some optimism for the future. We don’t have to sit around and watch this world burn like Sodom and Gomorrah. In the end, the Great Commission is fulfilled, the gospel flourishes, the nations are converted, and Jesus wins. So cheer up, buttercup.
