Scripture requires a high view of creation and of cultural activity, but it also requires a distinction between the holy things of Christ’s heavenly kingdom and the common things of the present world. It requires a distinction between God’s providential sustaining of human culture for the whole of the human race and his glorious redemption of a chosen people that he has gathered into a church now and will gather into the new creation for eternity. Some people indeed fall into unwarranted “dualisms,” but dualism-phobia must not override our ability to make clear and necessary distinctions. Some people indeed are guilty of promoting a godless and amoral “secular” realm, but the fear of a godless secularism should not eliminate our ability to speak of a divinely-ordained common kingdom that is legitimate but not holy. The two-kingdoms doctrine enables us to affirm the goodness of creation and culture without losing sight of crucial distinctions. The two-kingdoms doctrine helps us to account for the whole biblical story.
