5. By over-qualifying applications
Sometimes we make an application of a passage, but then feel the need to qualify it and state all the ways that might not be the way to act. Some qualification may be necessary or even vital, but trying to cover every possible misapplication can mean the actual application is lost in the mix.
6. By unnecessary balancing of the teaching of this passage
Just as with an application, so with the teaching of a passage. Perhaps your passage is speaking of the opposition of the world to followers of Christ . . . but if you over-qualify this with our need to influence the world (salt of the earth, etc.), then it will dissipate the passage you are preaching. Consider whether the balancing needs to be done in this message, or by preaching another passage another time.
7. By equally weighting every detail in the passage
Every passage consists of details – some weightier than others. Part of our task is to weigh up the relative influence of each on the summation of the whole. If we treat every word or every phrase equally, then we will lose the full impact of the actual message. Consider 2Tim.4:1-5 . . . is “preach the word” worthy of equal attention as “always be sober-minded” in the explanation of the passage?
8. By over-extending the landing
Some of the best sermons lose all their impact by the extra five minutes tacked on the end. Nail it and stop. Hard to do though. I could say more, but won’t.
