God Who is There by Francis A Schaeffer
There are few minds in the world which truly have been able to see clearly through all the muddle and fluff of the "politically correct" baggage that abounds in today's culture. Francis Schaeffer possessed one such mind. Insightful as very few have ever been, Francis "cuts to the chase" on the existence of God. The only book I have ever read which surpasses Schaeffer's writings is "The Existence and Attributes of God" by Stephen Charnock and, of course, the Bible itself. Brilliantly written. Absolutely true. Great book!
