The Dividing Line by Mark Sidwell, an unashamed Fundamentalist, will help any reader understand biblical separation, apply it, and practice it. A dividing line exists between truth and error. Separation involves discerning those lines between truth and error, between obedience and disobedience. Scripture has much to say about the Christian’s separation from worldliness, from false teachers, and even from disobedient brothers. Sidwell defends the biblical position that Fundamentalists affirm and shows where the Bible draws the dividing lines of separation but also reveals where contemporary movements stand in the light of these principles.
