"Now I want you to remember something because I don't think w..." — Robertson Davies quote meaning

Now I want you to remember something because I don't think we shall meet again very soon. It is this; however fashionable despair about the world and about people may be at present, and however powerful despair may become in the future, not everybody, or even most people, think and live fashionably; virtue and honour will not be banished from the world, however many popular moralists and panicky journalists say so. Sacrifice will not cease to be because psychiatrists have popularized the idea that there is often some concealed, self-serving element in it; theologians always knew that. Nor do I think love as a high condition of honour will be lost; it is a pattern in the spirit, and people long to make the pattern a reality in their own lives, whatever means they take to do so. In short, Davey, God is not dead. And I can assure you God is not mocked.
