On how a loving community is an apologetic for the gospel:
“And if we are surrounded by a world which no longer believes in the concept of truth, certainly we cannot expect people to have any interest in whether a man’s doctrine is correct or not. But Jesus did give the mark that will arrest the attention of the world, even the attention of the modern man… Because every man is made in the image of God and has therefore aspirations for love. There is something that can be in every geographical climate, in every point of time, which cannot fail to arrest his attention. What is it? The love that true Christians show for each other, and not just their own party” (Francis Schaeffer, The Mark of the Christian).
