Of all the sermons that have been preached, none is more famous, more profound, or more convicting than the one Jesus preached on the mountain. It is timeless, ever-relevant, and never dull. With penetrating power, Jesus exploded the brittle veneer of Pharisaic hypocrisy and explained the essence of true righteousness. Weaving threads from the Old Testament through this new garment of truth, Jesus set forth principles that, to this day, refuse to be ignored. Yet how few truly embrace His words! We analyze and interpret them. We outline and compare them. We admire and quote them. But those activities, while worthwhile, are not the reason Jesus preached this sermon. He preached it so that change might occur—so our lives might be different in this world gone wrong. God’s people are to be thoroughly Christian—a divine minority who live in contrast to a secular majority.
