If we are honest, we freely admit that the Christian system involves difficulties; but so does every other system. No thoughtful person gives up a position merely because he finds difficulties in it; he does not abandon it until he is able to find other and alternative systems with fewer difficulties... I learned from my professors of philosophy... that, while philosophy might not provide me with a watertight intellectual defense of the Christian faith, it would, if used aright, help me to reveal the weakness of its enemies. By careful analysis it is possible to see that there are glaring weaknesses and non-sequiturs in atheism, naturalism, positivism, scientism, and psychologism. The Christian must be a fighter, for he is always under attack. The Church will not be as strong as it ought to be until each local pastor uses his precious freedom from outside employment in order to become a scholarly participant in the intellectual struggle of our day and generation.
