Schaeffer said modern man is split. We are just matter in motion, and that's the fact of the real world. If there is to be meaning and significance it must come from somewhere other than the real world. It must be invented in our imagination and believed against the facts through an irrational leap of faith. This Schaeffer calls the second- story leap.
Man invents significance, value, and morality by making a blind leap of faith into the upper story.
Religions are concerned with spiritual matters that are subjective, personal, and private. One need have no proof or justification for one's spiritual beliefs because no one has the right to presume to judge the validity of those beliefs. This writer makes it very clear that his view is that religious belief is in a separate category from fact. It is just a mere belief. It is an invention of your own mind and has nothing to do with the real world.
