Without oxen a stable stays clean, but you need a strong ox for a large harvest. (Proverbs 14:4 NLT)
Is your church building spotlessly clean? Well, that might not be as good a thing as some people seem to think. If it's clean because there is very little use of the facilities, then your cleanliness is not really next to godliness. On the other hand, if it's somewhat disheveled from its constant use by the busy flow of people, then God is actually blessed by the mess. Wherever there's a "large harvest," it's inevitable that the "stable" is going to be a little less tidy. Don't complain about it, thank God for the people He's giving you and then go help clean up the mess.
