Jesus said, “You shall love the Lord your God with all your heart, and with all your soul, and with all your mind, and with all your strength” (Mark 12:30). Loving God with the mind is not a passive process. It is not enough to have sentimental religious thoughts. Rather, it involves coming to conclusions about God and his world based on revelation, observation, and careful reflection. — Greg Koukl (from, Tactics: A Game Plan for Discussing Your Christian Convictions)
