Why Is the Sermon So Important?

To understand why the sermon holds such a central place in Lutheran worship, you have to see what Lutherans believe preaching actually is. It is not, at its heart, a religious lecture, a motivational talk, or the pastor’s personal opinions dressed up with Bible verses. Faithful preaching is a means of grace—one of the very ways God delivers Christ and creates faith. When the Word is rightly preached, God himself is speaking and acting through it.

Scripture makes this astonishing claim directly. Faith, Paul says, “comes from hearing, and hearing through the word of Christ” (Romans 10:17); and how will people believe “without someone preaching?” (Romans 10:14). God has chosen “through the folly of what we preach to save those who believe” (1 Corinthians 1:21). Preaching is not incidental to God’s saving work—it is a primary instrument of it. The Thessalonians received Paul’s preaching “not as the word of men but as what it really is, the word of God, which is at work in you believers” (1 Thessalonians 2:13). That is exactly how Lutherans understand the sermon: God’s own Word, at work.

This is why the sermon is not merely to inform but to deliver—to apply God’s Law that exposes sin and, above all, God’s Gospel that gives Christ and forgiveness to the hearers. A good Lutheran sermon is measured not by cleverness, entertainment, or practical tips, but by one question: was Christ crucified and risen proclaimed, and were Law and Gospel rightly distinguished, so that sinners were given a Savior? The pastor is called and ordained precisely for this public proclamation (Augsburg Confession V, XXVIII).

So “isn’t it just one person’s opinions?” gets the answer: it shouldn’t be, and when it is, it has failed. The preacher’s job is not to offer his views but to proclaim God’s Word faithfully—to “preach the word… in season and out of season” (2 Timothy 4:2). Where he does that, you are not listening to a man’s opinions; you are hearing God address you, forgive you, and strengthen your faith. That is why Lutherans will not reduce the sermon to a warm-up or an afterthought. It is one of the places God has promised to meet you—and to give you Christ.
