We are living in a period of church history that may be classified as mindless. It is an anti-intellectual period of Christian history—not anti-scientific, or anti-technological, or even anti-educational, but anti-mind. While teaching in a seminary classroom I would sometimes ask a student what he thought about a particular proposition. The student would sometimes respond, “I feel that the statement is incorrect.” I would stop him and say, “I didn’t ask you how you felt. I wasn’t inquiring into your emotional response. I was asking you what you think about it.”
Thinking is done by the mind, and Christians are called repeatedly in sacred Scripture not to leave their minds in the parking lot when they enter into church but to awaken their minds so that they may think clearly and deeply about the things of God. Some people say that God does not care about the mind but only the heart and that an emphasis on the mind leads to rationalism, and from there to modernism, postmodernism, and all else that stands in antithesis to biblical Christianity. It is true that what you think in your mind will never get you into the kingdom of God until it reaches your heart, but we have been created by God in such a way that the pathway to the heart is through the mind. We cannot love with passion that which we know nothing about. The book that contains the sacred revelation of Almighty God, His Word, is addressed in the first instance to our minds. Therefore, the more we understand the truth of God, the more we will be gripped by it in our hearts and changed by it.
