How must we live in order to be, or to become, capable of happiness? The question is one which ought to occupy us nowadays more than ever before. Man should take his happiness as seriously as takes himself. And he ought to believe God and his own heart when, even in distress and trouble, he has an intuitive feeling that he was created for happiness.
But this entails certain clear convictions. For a full and satisfying life man must know what it is all about. He must have no doubts about being on the right road with all the saints to back him up, and divine strength to support him. Such a life is a dedicated one, conscious of being blessed and touched by God himself.
