What Is the Sermon on the Mount?

Understanding Matthew 5-7

The Sermon on the Mount, recorded in Matthew chapters 5 through 7, is the longest continuous teaching of Jesus in the Gospels and arguably the most influential speech in human history. Delivered on a hillside near the Sea of Galilee (traditionally identified as the Mount of Beatitudes near Capernaum), it lays out the ethics, values, and spiritual practices of the kingdom of God.

Structure and overview

The sermon has a clear structure:

1. The Beatitudes (Matthew 5:3-12) — Eight declarations of blessing that invert worldly values:

• Blessed are the poor in spirit — the kingdom belongs to them
• Blessed are those who mourn — they will be comforted
• Blessed are the meek — they will inherit the earth
• Blessed are those who hunger and thirst for righteousness — they will be filled
• Blessed are the merciful — they will receive mercy
• Blessed are the pure in heart — they will see God
• Blessed are the peacemakers — they will be called children of God
• Blessed are those who are persecuted for righteousness — the kingdom belongs to them

The word 'blessed' (makarios in Greek) does not mean 'happy' in the modern sense. It means deeply, genuinely fortunate — favored by God in a way that transcends circumstances.

2. Salt and Light (Matthew 5:13-16) — Jesus calls His followers 'the salt of the earth' and 'the light of the world.' Salt preserves and flavors; light reveals and guides. Christians are to be a visible, transformative presence in the world — not withdrawn or hidden.

3. Jesus and the Law (Matthew 5:17-48) — Jesus does not abolish the Old Testament Law but deepens it radically:

• Murder → Do not even harbor anger or contempt (5:21-26)
• Adultery → Do not even look at someone with lust (5:27-30)
• Divorce → Marriage is binding; do not treat it casually (5:31-32)
• Oaths → Let your yes be yes and your no be no (5:33-37)
• Retaliation → Turn the other cheek; go the second mile (5:38-42)
• Love → Love your enemies and pray for those who persecute you (5:43-48)

The pattern is clear: the Law addressed external behavior; Jesus addresses the heart. It is not enough to avoid murder — you must root out the contempt that leads to it. It is not enough to avoid adultery — you must discipline your inner life.

The climax: 'Be perfect, therefore, as your heavenly Father is perfect' (5:48). This is not a demand for sinlessness but a call to completeness — love that extends to everyone, including enemies, just as God's love does.

4. Spiritual practices (Matthew 6:1-18) — Jesus addresses three core practices of Jewish piety:

• Giving (6:1-4) — Give secretly, not for public recognition
• Prayer (6:5-15) — Pray sincerely, not to impress others. Includes the Lord's Prayer (6:9-13), the most prayed prayer in history
• Fasting (6:16-18) — Fast without making a show of it

The consistent principle: God sees what is done in secret and rewards it. Spiritual practices performed for human approval have already received their full reward — applause.

5. The Lord's Prayer (Matthew 6:9-13)

'Our Father in heaven, hallowed be your name, your kingdom come, your will be done, on earth as it is in heaven. Give us today our daily bread. And forgive us our debts, as we also have forgiven our debtors. And lead us not into temptation, but deliver us from the evil one.'

This prayer is a masterclass in theological priority: God's name, God's kingdom, and God's will come before human needs. When human needs are mentioned — bread, forgiveness, protection — they are framed communally ('us,' 'our') and simply.

6. Money, worry, and priorities (Matthew 6:19-34) — 'You cannot serve both God and money' (6:24). 'Do not worry about your life' (6:25). 'Seek first his kingdom and his righteousness, and all these things will be given to you as well' (6:33). This section directly challenges the human tendency to find security in wealth and to be consumed by anxiety about material provision.

7. Judging others (Matthew 7:1-6) — 'Do not judge, or you too will be judged' (7:1). This is not a prohibition against all moral discernment — Jesus immediately tells listeners to identify 'dogs' and 'pigs' (7:6), which requires judgment. The prohibition is against hypocritical judgment — condemning others for faults you share: 'First take the plank out of your own eye, and then you will see clearly to remove the speck from your brother's eye' (7:5).

8. Ask, seek, knock (Matthew 7:7-12) — A promise of God's responsiveness to prayer, culminating in the Golden Rule: 'So in everything, do to others what you would have them do to you, for this sums up the Law and the Prophets' (7:12). This one sentence summarizes the ethical teaching of the entire Old Testament.

9. Two paths, two trees, two builders (Matthew 7:13-27) — The sermon closes with three sharp contrasts:

• The narrow gate vs. the wide gate (7:13-14) — few find the path to life
• Good trees vs. bad trees (7:15-23) — people are known by their fruit, not their claims
• The wise builder vs. the foolish builder (7:24-27) — hearing Jesus' words and doing them is the only firm foundation

The crowd's response:

'When Jesus had finished saying these things, the crowds were amazed at his teaching, because he taught as one who had authority, and not as their teachers of the law' (Matthew 7:28-29). The rabbis taught by citing other rabbis. Jesus taught on His own authority: 'You have heard that it was said... but I tell you.' This implicit claim to authority equal to or greater than Moses was not lost on His audience.

Major interpretive approaches:

1. A literal ethic for all Christians — The sermon means exactly what it says. Turn the other cheek. Do not resist evil. Give to everyone who asks. This view, held by Anabaptists (Mennonites, Amish), Leo Tolstoy, and some others, takes the commands at face value and attempts to live them directly.

2. An impossible ideal that reveals our need for grace — Martin Luther argued that the sermon shows how far short we fall, driving us to depend on Christ's righteousness rather than our own. We cannot perfectly love our enemies or eliminate lust — but we can trust the One who did.

3. Kingdom ethics for the coming age — Albert Schweitzer and others saw these commands as 'interim ethics' for the brief period before the expected end of the world. Few hold this view today in its pure form.

4. A vision of transformed character — Dallas Willard and others emphasize that Jesus is describing the kind of person who naturally lives this way — someone whose heart has been transformed by God's grace. The sermon is not a new set of rules but a portrait of a new kind of human.

Why it matters:

The Sermon on the Mount has shaped ethics, law, politics, and culture more than any other speech. Gandhi was profoundly influenced by it (particularly 'turn the other cheek'). Martin Luther King Jr. built the civil rights movement on its principles. It has been called 'the nearest thing to a manifesto that Jesus ever uttered.'

Whether you read it as literal commands, an impossible ideal, or a vision of transformed humanity, the Sermon on the Mount confronts every reader with the same uncomfortable truth: the kingdom of God operates on radically different principles than the kingdoms of this world. And Jesus expects His followers to live by those principles — not someday, but now.
