Darrow Miller shared a moment from his lifestory:
One of the milestones in my life was 1969 in L’Abri, Switzerland. Marilyn and I were studying with the Schaeffers. We were living in the home of Udo and Debbie (Schaeffer) Middelmann. One Sunday evening Udo said to me “You know, Christianity is true even if you do not believe it!” These words were a shock to me. In church, in my discipleship program, and in seminary, I had been taught that Christianity was true precisely because I believed it.
After two sleepless nights, I realized what Udo was saying. Christianity is true, even if no one in the world believed it. It is true because God exists! It is true to reality! It was at that moment that I realized that I had a “born again” heart, but my mind had never been born again. I had the mind of an atheistic materialist. If there is no God, there is no truth. All things (including morals and beauty, for example) are relative. Your truth is whatever you choose to believe.
