Facilitation is not about people listening to you give a sermon.  Facilitation is about you promoting true learning.  True learning is when people internalize a subject so it becomes part of them---they no longer have to think about it, it's just there.  That's not just sitting in a lecture.  It's you taking the information that's potentially useful to you and applying it.  Facilitation helps people apply information of use to them.  That's engagement with a topic on a personal level.  Facilitators help a small group of people engage personally with a topic by directing conversation, allowing the people to struggle with the topic as it best applies to their own lives.  For example: instead of "listen to my lecture" it's "what do you think on this topic.  Jane, you first.  Then John, then George, then Alice...on around the group.  We'll listen and comment on each other's ideas in turns.  Meanwhile, I'll be taking the key information you come up with up here on the flip-chart.  Afterwards, we'll consider how to put things together to arrive at a group conclusion."  This is a whole different thing than a sermon: i.e. instead of the expert lecturing, it's where the fully mutually-informed group is considered "smarter" than any single person, including the preacher!
