People who do good things but don't know why

When a sermon does not under-gird its practical applications with biblical theology, it is merely raising up people who do good things but don't know why.

Sometimes, people ask for sermons to be more practical. They want the preacher to give a memorable acronym that instructs us how to be better brothers and sisters, or a better employee, or how to care for the poor and sick. Of course, practical applications are great. But what good are they if the listener has no idea where they came from?

As I consider my church, I deeply fear that some thirty years later, we'll become a group of people who do good things but don't know why.
