“The evidential apologist believes that there is a neutral place where a Christian may encounter an unbeliever, agree on some common ground rules, and reason from that neutral place to a faith in the God of the Bible. The presuppositional apologist, on the other hand, argues that there is no such neutral place, and that all reasoning presupposes, of necessity, the triune God of Scripture.”
