The proposition is one of the most important aids in creating a sermon. It is a single simple sentence that summarizes the one big idea of the passage.
One word of encouragement is that once you have the proposition, the hardest part is done. The rest of the sermon will probably take longer to complete, but it will not be as difficult to accomplish.
