There's a twisting, mountainous road in northern Scotland which had, almost to the top, a steep sharp curve where there was a slight widening of the road. Many years ago, someone put a park bench there, and it forever became known as the Rest and Be Thankful. Its nickname stuck, long after the road was straightened and widened, once the crooked was made straight and the rough places plain. And it entered into our language as a phrase with much deeper meaning.
So today, my sabbath day, the phrase comes to me...rest, and be thankful.
