Great preaching has a practical bent. It helps real people deal with real issues that they deal with in real life. Often preachers when confronted with this reality will skimp on the doctrine. They end up addressing issues in a topical manner without applying the foundation of a doctrine based in sound theology.
Sometimes preachers even go so far as to denigrate doctrine as useless and unprofitable. But without sound doctrine you are rudderless. You are simply drifting about without any real rock. The Bible author said that there would come a time when people would not endure sound doctrine (2 Timothy 4:2-3).
The issue is not preaching “practical” sermons instead of “theological” or “doctrinal” ones. The issue is demonstrating to your people the different doctrine makes in real life. No it is a false dichotomy to separate practical from theological. Go head on and preach your doctrine. Preach the doctrines that are in your own ecclesial tradition. But as you do it, please let the people know why it matters.
I repeat we don’t have a dichotomy between “doctrine” and “Jesus.” Please don’t continue this false dichotomy. If you are forever putting down doctrines then you will help create a people who “can not endure sound doctrine.”
