In Isaiah 6, the Lord tells the prophet Isaiah to go preach to hardhearted people. Extrapolating from Isaiah’s context, this would include both the churched and the unchurched. And what was the promised result of his preaching? The result, the Lord says, will be that ninety percent of his audience will fall away. In this case, God promises Isaiah a radical decline in numbers. The decline is just as much a move of God as a radical increase might be.
