"... the happiness of the soul consists in the exercise of the affections; ... As hunger and thirst, as taste, sound, and smell, are the channels through which this bodily frame receives pleasure, so the affections are the instruments by which the soul has pleasure. When they are exercised duly, it is happy; when they are undeveloped, restrained, or thwarted, it is not happy. This is our real and true bliss, ... to love, to hope, to joy, to admire, to revere, to adore. Our real and true bliss lies in the possession of those objects on which our hearts may rest and be satisfied... the thought of God, and nothing short of it, is the happiness of man; for though there is much besides to serve as subject of knowledge, or motive for action, or means of excitement, yet the affections require a something more vast and more enduring than anything created. .. He alone is sufficient for the heart."
