Each theological seminary tends to magnify one style over others.
Some formats are "self-determining," that is: they have their main points dictated by Scripture.
Other types of "preaching" involve inserting the ideas and philosophies of the "Preacher" into them.
The most difficult style of preaching, and the most likely to err, is topical preaching.
In it, the "preacher" selects a TOPIC (led, of course, by the Holy Spirit). He then sets about the task of developing the topic, using Scripture verses to back his point of view.
One major issue with this preaching approach is that the preacher must constantly guard against allowing his point of view to supersede the view of Scripture on the subject.
He must also avoid using Scripture verses out of their context to "prove" his point.
Often, the verses chosen are really teaching an opposite principle, but because they sound right, seem "spiritual" or use language that makes them seem as though they "fit" the topic, he uses them, blithely disregarding their true meaning.
For example, suppose a preacher wanted his listeners to learn the importance of listening carefully, studying hard, becoming wise and doing the right thing.
He might search Scripture until he found Job 34:2-4. Hear my words, you wise men, listen to me, you men of learning. For the ear tests words as the tongue tastes food. Let us discern for ourselves what is right; let us learn together what is good.
"Sounds good," you say.
Maybe so, but it would be an abomination to use those verses to teach the lesson he wanted learned, because they are the words of Elihu, about whom God, Himself, said, (speaking to Eliphaz) "I am angry with you and your two friends, because you have not spoken of me what is right, as my servant Job has."
In fact, here is why God would be angry about Elihu making that statement:
1. It is self-serving. Count the number of times he refers to himself.
2. It is being used to accuse Job of doing that of which he is innocent.
3. It suggests that men determine what is right on their own...a very common approach in even today's secular society.
4. It teaches that together we can learn what is good, apart from God.
Now Job is a perfectly good book of the Bible...of course.
But one must be very careful about quoting Job, for it is replete with traps just like the one above.
In fact, to quote what Job says is to reveal his despair.
To quote what God says reveals His character, love and long-suffering.
But to quote Eliphaz, Bildad, Zophar or Elihu as though they have anything constructive to say is to reveal one's total misunderstanding of the point of the book of Job, which is:
Religious people (Job's accusers) tend to misuse truths about God to beat the faithful over the head, especially when they are down, and God does not like that.
Two-thirds of the book deals exactly with that issue.
In fact, so many people misuse the book of Job, that I wonder whether they know how to read at all.
Job was not patient, yet we speak of the "patience of Job."
Job was righteous...God said so, yet we try to figure out what he did wrong to deserve his travails.
Job was depressed, wishing he had never been born.
Job was angry with God, questioning His motives and actions.
But Job was faithful.
For the faithful...truly faithful...the reward is beyond our wildest dreams.
A pastor once said to me, "There may be one meaning to a Scripture verse, but there are many applications."
Poppycock!
God's Word means what it means. Otherwise it would be arbitrary and capricious, and one could never be certain of its meaning. Its "meaning" would be subject to various interpretations and winds of doctrine.
If you are going to preach topically, at least let the Scripture dictate your topics and don't try to "proof-text" your sermons.After all, not one soul on earth needs a behavioristic religious philosophy lesson.
Few souls on earth care about your "life systemology."
What they need is to hear the Word of God rightly divided.
The Bible is God' revelation of His character, His love for His Creation and His plan for its redemption.
