Sometimes people try to justify their lack of intellectual engagement by asserting that they prefer having a “simple faith.” But here I think we must distinguish between a childlike faith and a childish faith. A childlike faith is a whole-souled trust in God as one’s loving Heavenly Father, and Jesus commends such a faith to us. But a childish faith is an immature, unreflective faith, and such a faith is not commended to us. On the contrary, Paul says, “Do not be children in your thinking; be babes in evil, but in thinking be mature” (1 Cor. 14.20 RSV). If a “simple” faith means an unreflective, ignorant faith, then we should want none of it. In my own life, I can testify that, after many years of study, my worship of God is deeper precisely because of, and not in spite of, my philosophical and theological studies. In every area I have intensely researched—creation, the resurrection, divine omniscience, divine eternity, divine aseity—my appreciation of God’s truth and my awe of His personhood have become more profound. I am excited about future study because of the deeper appreciation I am sure it will bring me of God’s personhood and work. Christian faith is not an apathetic faith, a brain-dead faith, but a living, inquiring faith. As Anselm put it, ours is a faith that seeks understanding.
Furthermore, the results of being in intellectual neutral extend far beyond one’s own self. If Christian laymen do not become intellectually engaged, then we are in serious danger of losing our youth. In high school and college, Christian teenagers are intellectually assaulted by every manner of non-Christian philosophy conjoined with an overwhelming relativism. As I speak in churches around the country, I constantly meet parents whose children have lost their faith because there was no one in the church to answer their questions. In fact, George Barna estimates that 40% of the youth in our churches, once they leave for college, will never darken the door of a church again. — William Lane Craig (from, In Intellectual Neutral)
