Indeed, head knowledge without adequate “heart knowledge” can be spiritually disastrous. The moral failure of many highly intellectual “men of God” is a case in point.
George Verwer of Operation Mobilisation recalled the time when he went with someone to the office of Billy Graham. None of the office staff noticed them except the receptionist. They were too pre-occupied with an evangelistic campaign to pay attention to outsiders. Then Graham walked in and started shaking hands with everybody. He went over to greet both Verwer and his friend. Though much busier than the office staff, he had time to spare for others. He was full of warmth and love. Similarly, ministers and theologians must remain down-to-earth and be able to connect with ordinary folks.
