One might do something for his whole life and accomplish it to a great extent. And by the lack of a little more faith one would lose it, and all that was done might be spoiled in a moment's time. How long does it take for a house to be built, and how long does it take to destroy it? How long does it take to make a business really prosperous, and how long does it take to fail? One moment. When one learns this principle and thinks on it, one begins to see that the whole world, with all that we hear and see and touch and feel, all this is illusion in the face of faith. Faith alone is reality; and compared with faith all else is unreal. But since we do not see faith with our own eyes, it is very difficult to call faith real and all else unreal. Because we don't see faith, our eyes cannot see it and we don't know where it is.
