In the 36 years I've been in ordained ministry there have been many theories about how to grow a church and what people are seeking in their churches. A growing church holds a conference explaining what they did to cause their church to grow and that theory becomes the latest fad. Suddenly, all around the country churches begin to copy the model they were taught and are surprised to find that their church still didn't grow.
Let's forget about the growth aspect for a moment and just focus on what people are wanting in the churches they attend. According to a recent poll the number one thing people want in their church is preaching that is based on the Bible.
I encourage you to read this excellent article by Tim Challies on what this means going forward.
