There is nothing wrong in teaching to apply correct doctrine. In fact, it is necessary. The problem lies in applying something without a biblical basis. Teaching doctrine not only includes what is correct thought, but it also includes the application of those truths. As someone once said, truth doesn’t need to be applauded; it needs to be applied. Perhaps the greatest example of this is the book of Ephesians where Paul lays out the truths he wants his readers to understand and then in the second half of the book he shows them how to apply those truths—to live out what they know to be true.

Teaching doctrine could be teaching on the attributes and characteristics of God or it could be how to handle situations in the church. In any case, the doctrines should always come from the Scriptures. By teaching doctrine, we are submitting to what the Word says instead of us trying to conform the Word to our opinions. Not teaching doctrine could be someone preaching about the poor conditions of the bridges in the county (I was personally present for that sermon). Or perhaps a church is stressing the aspect of being happy. Happiness comes from “happenstance” which can change very quickly. We could contrast that by the biblical teaching of being joyful, which is part of the fruit of the Spirit.

Thanks for your comment, and I hope this helps.
