We are talking about real truth, and not something vaguely religious which seems to work psychologically…. We are talking about real guilt before God…. We are talking … about real history, that the death of Jesus was not just an ideal or a symbol, but a fact of space and time…. Until he understands the importance of these three things, he is not ready to become a Christian.
— Francis Schaeffer, quoted in Ambassador’s Guide to Postmodernism by Greg Koukl, p. 58
