All we can know is, what we, who compose humanity, must do, and what not, in order that the kingdom of God may come. That we all know. And every one need but begin to do what we must do, and stop doing what we must not do; every one of us need only live by all that light which is within us, in order that the promised kingdom of God, toward which the heart of every [one] is drawn, may come at once.
–Leo Tolstoy, The Kingdom of God Is Within You
