Sermon response

The aim of any sermon is to get some kind of response.
Enlightenment. Repentance. Encouragement. Conviction. Enablement.

And I've been in some sermons where the only response has been boredom.
I've probably caused that reaction a few times...

But I wonder how many people at church are aware that the way they respond to the sermon is a message in itself.

Especially to those who are new to your church or just "checking out the whole God thing."

If you're engaged with the sermon, then it tells those around you that what's going on matters.

If you're disengaged - looking at your phone, speaking to the person beside you, obviously drifting off into space - then it sends the message to those around you that what's going on isn't important.

If we want people to know about the life changing message of Jesus, and one way that message in communicated is via a sermon, then I wonder what a seeker thinks when a believer is outwardly unmoved by what's going on?
