The first logical step in preparing a message (once you’ve been asked to preach, which is presumed), is to select your passage(s) on which to base the message. Sometimes the invitation comes with the passage, sometimes with a theme, sometimes an open invitation. Select then forget. What do I mean?
1. When you’re invited to preach with a passage assigned. You may be tempted to skip the Passage Selection phase of preparation altogether, after all, job is already done, isn’t it? Well, not fully. You need to double check that you are handling a full unit of thought (i.e. not half a story, half a proverb, half a psalm, half a paragraph, etc.) Whatever you are asked to preach, you have to study the full unit of thought in its context, so there is a need to check the selection. In doing so, especially if a title has been assigned, you may get a clear indication of what they are wanting from the message. Great, a church or ministry being purposeful is a good thing. But for the study phase (stages 2-4), you need to forget that purpose and seek to dwell in the text. Reintroduce that purpose in your thoughts for message purpose, stage 5.
2. When you’re invited to preach with a theme assigned. You go on the hunt for an appropriate passage on which to preach that theme (or a combination of passages). Once you’ve selected your passages, forget the theme for a while. The text has to be free to speak for itself. Any imposed message makes it something other than truly biblical preaching.
3. When you’re invited to preach and free to choose. This is hard work. You can easily waste a lot of time pondering where to go. You may go where you go for a variety of reasons, but once you’ve gone there, forget your motivation (for now) and allow the text to speak for itself.
What if it is different? At times I’ve been faced with a passage that doesn’t do what I thought it would, or doesn’t do what a title suggests. Well, then, either preach the passage or pick another. Simple really, but vital. When we are studying passage (stages 2-4), we need to let the text be boss, and then let that authority linger through the message formation phase of the process.
