For years my application had exactly one shape. What will you do about this before next Sunday? It is a fair question. It was directed at the members of my church, calling them to live out the gospel in practical, personal ways.
The problem: we preach letters written to churches as if they were addressed to individuals.
The New Testament letters were written to congregations. The "you" in Ephesians is plural almost every time it appears. When Paul tells the Philippians to work out their salvation with fear and trembling, he is addressing a church about its common life, and most of us have preached that verse as a personal assignment for the coming week. The text said us. The sermon said you.
Pro-tip: If every application in your sermon could be obeyed alone in a locked room, you preached to individuals who happened to be seated together.
The instinct behind it is not wrong. Individual obedience is real, and a sermon that never lands on a single conscience has failed differently. Nobody repents as a committee. But when personal application is the only mode available, you have fifty people hearing fifty private sermons in the same room, and the congregation slowly learns that church is where you go to collect your instructions for the week.
The discipline is one application per sermon aimed at the body. Not fifty individuals in parallel. The church. What does this passage ask of us as a people who belong to each other? Sometimes that is corporate confession. Sometimes it is a practice the congregation takes up together, or a way the members are meant to carry something for one another that none of them could carry alone. Write that application the way you would write any other, with the same specificity, and say it out loud in the sermon.
A church is not an audience that happens to arrive at the same time.
Preach to the people of God, not just to the people in the room.
