Calvin on the relationship between the location of our happiness and the measure of our faith

Not only does he sustain this universe (as he once founded it) by his boundless might, regulate it by his wisdom, preserve it by his goodness, and especially rule mankind by his righteousness and judgment, bear with it in his mercy, watch over it by his protection; but also that no drop will be found either of wisdom and light, or of righteousness or power or rectitude, or of genuine truth, which does not flow from him, and of which he is not the cause...I call ‘piety’ that reverence joined with love of God which the knowledge of his benefits induces. For until men recognize that they owe everything to God, that they are nourished by his fatherly care, that he is the Author of their every good, that they should seek nothing beyond him - they will never yield him willing service. Nay, unless they establish their complete happiness in him, they will never give themselves truly and sincerely to him.
