The weakness of so many modern Christians is that they feel too much at home in the world. In their effort to achieve restful adjustment to unregenerate society they have lost their pilgrim character and become an essential part of the very moral order against which they are sent to protest. The world recognizes them and accepts them for what they are. And this is the saddest thing that can be said about them. They are not lonely, but neither are they saints.
