This paper outlines a constructive account of natural law for the twenty-first century, rooted in the Reformed theological and confession heritage. It suggests how natural law can provide us with a deep theological way of affirming the existence of an objectively meaningful natural order, discusses the importance of natural law for maintaining the accountability of all human beings before the divine judgment, and reflects on how natural law serves as crucial foundation for the church's ministry of the gospel to a hurting and needy world.
