There are many things that preachers/bloggers do to stretch a sermon/blog post out. Sometimes they will repeat their points several times in different ways, or they will tell anecdotes that illustrate their point. These things are all legitimate: in fact they are essential strategies in communicating true principles through words. However, one thing preachers must not do, is fill in the gaps with “filler” Philosophy. Any philosophy you hear from the pulpit that does not in some way bear on your relationship with Christ is dangerous:
See to it that no one takes you captive through hollow and deceptive philosophy, which depends on human tradition and the elemental spiritual forces of this world rather than on Christ. (Colossians 2:8)
Sometimes preachers fall subconsciously for the argument that the gospel is not enough; that straight-forward doctrine is insufficient to provide meaning for people’s lives. So they add “filler” philosophy: words of wisdom that might not actually be true. All preachers do this by accident from time to time: they are only human. Every preacher needs to do his best to make sure that every sentence he preaches has a purpose. If he preaches a sentence with an unknown purpose he should watch out, for how does he know that sentence will be used for good and not for evil? Filler philosophy is dangerous because it takes the focus off Christ, and gives the misconception that there is a part of our life that can function well without being focused on Christ. A preacher may preach on any seemingly insignificant subject he likes, as long as his preaching always brings the focus back to Christ.
