I am often surprised (and equally appalled) at the lack of basic knowledge that too many ministers have about ordering worship.  Directed by others to this link, I was encouraged and discouraged in equal measure.  Encouraged because it's good stuff.  Discouraged because I've known this since I was a child.  Thankfully I grew up in, and have served in, churches who understand what the work of worship is.  Too many, it seems, do not.
