As with most books by Searcy you take the meat and throw out the bones - meaning there is a lot that will likely work in your context and things that won't. Keep what can be used and don't stress over trying to shoe horn things into your methodology that won't fit. I think this is something that Nelson would agree with.
"Engage" has a lot of practical wisdom for planning a church gathering/service. With a fair amount of practical stories and examples the book is easy to follow and visualize in action.
