content, and strategies of argumentation. Others viewed it as a form of discourse characterized by its tone and purpose. Biblical basis R. C. Sproul, quoting the First Epistle of Peter, writes that "The defense of the faith is not a luxury or intellectual vanity. It is a task appointed by God that you should be able to give a reason for the hope that is in you as you bear witness before the world."

Experiential apologetics Experiential apologetics is a reference to an appeal "primarily, if not exclusively, to experience as evidence for Christian faith."
