This book provides a thorough presentation of postmillennialism. Postmillennialism is the eschatological system of Scripture that holds that the gospel of Jesus Christ will gradually win world-wide sway. The postmillennialist believes that o ne day before Christ returns the world as a system will be Christianized, operating on biblical principles in all areas of life. This will lead to a long period in which righteousness, peace, and prosperity will prevail in the earth.

He Shall Have Dominion argues for Christianity's dominance in world affairs be means of scores of Bible verses and numerous theological observations. It provides three entire chapters answering objections to the postmillennial hope.
