How do we respond to the Sermon on the Mount? The Sermon on the Mount (Matthew 5-7) is the first step on the way of discipleship, and it is of decisive importance that the church consider this deeply. If we fully grasp the Sermon on the Mount and believe it, then nothing can frighten us – neither our own self-recognition, nor financial threats, nor our personal weakness.
The dedication demanded in the Sermon on the Mount is not a new law or moral teaching. Instead it is forgiveness. Its vital element is the light and warmth of the Holy Spirit. Here is Christ: the essence of salt, and the strength of the tree that bears good fruit. The Sermon on the Mount shows us the character of a community, which shines like a light for the whole world.
The Sermon on the Mount is not a high-tension moralism, but we must grasp it as the revelation of God’s real power in human life. If we take our surrender to God seriously and allow him to enter our lives as light, as the only energy which makes new life possible, then we will be able to live the new life.
If we see the Sermon on the Mount as five new commandments, as the Tolstoyans do, we will fall right into a trap. For in his book My Religion, Leo Tolstoy lists the commandments of Jesus from the Sermon on the Mount as five new laws: peacefulness with others, sexual purity and marital faithfulness, the refusal to swear oaths, nonresistance to evil, and love for one’s enemies. But Jesus shows us that the clarity and demands of the old laws are not weakened by his coming into the world; instead they are infinitely sharpened. Moreover, these are only five examples – there could be five hundred or five thousand –revealing the powerful effect of God’s work in Christ.
His righteousness, his justice, is better than anything scholars or theologians could offer. It is something absolutely different, and it does not depend on moral intentions and good ideas. The righteousness of the law can be fulfilled only through a new, organic way of living, through a life from God that flares up like light and sears and purifies like salt. It is like a flame that shines, like the sap that pulses through a tree. It is life!
