Anne Ortlund wrote a wonderful little book 35 years ago on the nature and practice of worship. She covers just about everything. At one point she offers this reflection which acts as a prism through which she begs us to ask - how and to whom and to what purpose do we gather as a people for worship.
"Every congregation has a choice to be one of two things. You can choose to be a bag of marbles, single units that don’t affect each other except in collision. On Sunday morning you can choose to go to church or to sleep in: who really cares whether there are 192 or 193 marbles in a bag?
Or you can choose to be a bag of grapes. The juices begin to mingle, and there is no way to extricate yourselves if you tried. Each is part of all. Part of the fragrance. Part of the 'stuff'." (p.102)
