To be ignorant and simple now — not to be able to meet the enemies on their own ground, would be to throw down our weapons, and to betray our uneducated brethren who have, under God, no defense but us against the intellectual attacks of the heathen. Good philosophy must exist, if for no other reason, because bad philosophy must be answered . . . The learned life then, is for some, a duty.
Too many believers have abandoned the learned life, so now the enemy’s voice bellows over the field of education and higher learning.
It may be even more simple than that. Current American Christianity as a whole would never be described by history as a generation who thought carefully about their beliefs. (I realize I’m painting with a broad brush.) This is why I appreciate the ministries of the late C. S. Lewis, Ravi Zacharias and Os Guinness to name a few. They don’t tell you what to think. They challenge your thinking. I don’t always agree with them, but they provoke me to explain why I disagree, which requires thought.
