Here is an excerpt from the essay referenced by Tom Woods.
“Isaiah had been very willing to take on the job – in fact, he had asked for it – but the prospect put a new face on the situation. It raised the obvious question: Why, if all that were so – if the enterprise were to be a failure from the start – was there any sense in starting it? “Ah,” the Lord said, “you do not get the point. There is a Remnant there that you know nothing about. They are obscure, unorganized, inarticulate, each one rubbing along as best he can. They need to be encouraged and braced up because when everything has gone completely to the dogs, they are the ones who will come back and build up a new society; and meanwhile, your preaching will reassure them and keep them hanging on. Your job is to take care of the Remnant, so be off now and set about it.”
