On Loving Those You Argue Against - Francis Schaeffer
"As I seek to do this [show a person the logical conclusions of his false presuppositions], I need to remind myself constantly that this is not a game I am playing. If I begin to enjoy it as a kind of intellectual exercise, then I am cruel and can expect no real spiritual results. As I push the man off his false balance, he must be able to feel that I care for him. Otherwise I will only end up destroying him, and the cruelty and ugliness of it all will destroy me as well. Merely to be abstract and cold is to show that I do not really believe this person to be created in God’s image and therefore one of my kind. Pushing him towards the logic of his presuppositions is going to cause him pain; therefore, I must not push any further than I need to."
