In the Old Testament we often find the Israelites "murmuring." What a wonderful expression. In the church we often find people murmuring, too. The only thing some people are willing to give is advice.

In 1884 in Princess Ida, W. S. Gilbert wrote a verse that must surely be the feeling of some Christians:
Oh don't the days seem lank and long
When all goes right and nothing goes wrong
And isn't life extremely flat
With nothing whatever to grumble at
