When the preacher is biblically faithful, this can be a beautiful demonstration of God gifting the church with shepherds and teachers (Ephesians 4:11). It may also expose a flaw: the preacher may not be training his flock how to read the Bible through his preaching.
Preachers need to see the preaching event as a key moment in church life that makes the Bible more “user friendly” for congregants. This will deepen their own time in the Word, growing them as disciples and equipping them for ministry (2 Timothy 3:16-17). Failing to do this will hinder spiritual growth by hindering Bible engagement, and could also leave congregants amazed at their preacher’s vast knowledge instead of what God has done for us in Jesus Christ.
Colin Marshall and Tony Payne address the importance of this in The Vine Project: Shaping Your Ministry Culture Around Disciple Making:
In his preaching, a pastor sounds the tuning fork so that the whole orchestra knows in what key to play. He teaches and guards the sound deposit of the gospel so that all may know it clearly and thoroughly (for how else will they speak it?). He shows them not only what the Bible says, but how they can read and speak that truth for themselves. He constantly teaches the sound doctrinal framework that shapes the Bible reading and speaking of the whole congregation. (117)
This way of thinking doesn’t require an extra twenty minutes of specialized instruction in each sermon.
What it does require is first understanding the text deeply and knowing how God wants to use it to shepherd hearts (often called the transformational intent of the passage). We will also want to know the challenges our congregants face approaching Scripture so we can properly address them (i.e. does biblical poetry confuse them?). Lastly, we will want to model faithful biblical interpretation by using basic hermeneutical principles to explain our thought process and conclusions. Below are several practical suggestions of how to implement this.
Just like people are more likely to embrace technology that is user-friendly, peppering your preaching with these suggestions over time will help your people better engage the Bible, which will nourish their faith, grow them in holiness, and spur them on to bear fruit.
And as that happens, there will be less magic tricks and exaltation of the preacher in favor of more “wow!” comments where they should be directed: God and His glory as revealed to us in Scripture.
