A mystery exists for believer and unbeliever alike, for earthly life is the same for them both. An infinite wall of which neither the ends nor the top nor the bottom can be seen.

Except, this wall, for the unbeliever, is an obstacle against which he vainly strikes his head.

While for the believer, it is a support, against which he leans to look back at life and ponder all its illogicality with more depth, power and certainty.
