Francis Schaeffer said himself that the heart of his apologetics can be found in three books, The God Who Is There, Escape From Reason, and He Is There and He Is Not Silent.
These three books together set forth an outline of how he defended and commended the truth of Christianity. He Is There and He Is Not Silent presents a basic Christian worldview in a more systematic way than the other two books. The lecture series that stands behind it, titled Possible Answers to Basic Philosophical Questions, illustrates how Schaeffer’s method works in practice.
Apologetic evangelist
I remember these lectures very well as I took them for one hour of seminary credits at Covenant Theological Seminary in St. Louis, Missouri. Schaeffer covered the three areas of existence, morals and knowledge, and showed how in each of these areas ‘modern-modern man’ (today he would say ‘postmodern man’) is left with only the hell of alienation. Christianity, on the other hand, gives answers that are satisfying both intellectually and personally, and allows for true beauty in each of the three areas. One young man, an unbeliever who had faithfully attended the whole week of lectures, became a Christian as the last one finished.
