I stole this quote from a Craig Groeschel talk on sex. It's a great principle which could revolutionize the way people approach ministry.
Statically, the church in America is in decline. Depending on who you trust, studies show somewhere between 60% and 90% of churched teenagers fall away from the faith after high school. Something is very wrong with the way we've been approaching ministry.
Insanity has been defined this way...
Doing the same thing but expecting a different result
How many churches fall into that category? If your ministry doesn't like the result you're getting, you need a new approach.
About five years ago I was interning at a church. The student pastor came to the conclusion we were producing a bunch of students with lots of knowledge on a variety of subjects, little knowledge of scripture, and little drive to serve. Every ministry we were doing was pretty much doing the same thing. So we stopped doing small groups. We canceled our Sunday night service, and we changed the focus of Sunday mornings. We shifted our focus to small groups on Sunday morning, and we started a service based ministry on Sunday nights. By making the shift we created an environment where students were both learning the Word and doing the Word.
If you don't like your current results, change your approach.
If you don't like the results of local churches, don't copy their approach.
