In expository preaching one goal is to make clear the meaning and significance of what is written in the passage.  That sounds relatively easy until you start considering specific passages.  You know the ones I mean.  The passages that you study for hours in order to understand what the author was saying.  In the process you work through numerous possible interpretations with multiple sets of evidence to support each interpretation.  It drives you to evaluate the accuracy and relative weight of these different pieces of evidence as you move toward an understanding of the passage.  In the end, Sunday comes and you sometimes have enough material to teach a seminary course on the passage.

The goal in preaching is to give the fruit of the study labor, not every detail of your behind the scenes work.  Select enough explanatory comments to demonstrate that your understanding is solidly based on the teaching of the text, otherwise your message will lack authority.  When you are not clear on the meaning of every element in the text, find the balance between recognizing the difficulty of the passage, but not undermining confidence in that which is clear.  Be careful that the goal of explaining the meaning does not crowd out presenting the relevance of the passage by means of application.  Don’t let heavy study turn a sermon into a lecture.

When we preach we seek to make clear the meaning and significance of the passage.  That takes prayerful care because it is not easy.  Pray that today’s message will be genuinely expository and pleasing to the Lord.  Pray that the Lord will be at work in the presentation of His Word to His people by you, His servant in the power of His Spirit.  We do our part, but it is not possible to achieve anything lasting with our part alone.
