Proper strategic planning may lead you to make appropriate worship changes, but doing so based upon an "if we change it, college students will come" mindset will not produce the desired results. In fact, doing so quite likely will upset a significant portion of your current worshipers.
We cannot improve God's inerrant Word, but we can get in its way. As such, worship needs to be done well, which requires sufficient preparation. Students do expect high quality. But your current worship style probably reflects your church's values, so there's probably no need to change it significantly unless you have more valid reasons to do so.
I can lead your church through an in-depth planning process to help it more clearly see God's vision for it. Email me at firstname.lastname@example.org to learn more.
