“Naked women + right hand = happy happy joy joy”

“The Christian is not superficial in any sense, but is fundamentally serious and fundamentally happy. You see, the joy of the Christian is a holy joy, the happiness of the Christian is a serious happiness. ... it is a solemn joy, it is a holy joy, it is a serious happiness; so that, though he is grave and sober-minded and serious, he is never cold and prohibitive.”

“Children at once accept joy and happiness with quick familiarity, being themselves naturally all happiness and joy. ”

“The difference between shallow happiness and a deep, sustaining joy is sorrow. Happiness lives where sorrow is not. When sorrow arrives, happiness dies. It can't stand pain. Joy, on the other hand, rises from sorrow and therefore can withstand all grief. Joy, by the grace of God, is the transfiguration of suffering into endurance, and of endurance into character, and of character into hope--and the hope that has become our joy does not (as happiness must for those who depend up on it) disappoint us.”

“The fact is always obvious much too late, but the most singular difference between happiness and joy is that happiness is a solid and joy a liquid.”

“The "supreme good" and its attainment -- that is happiness. And joy is: response to happiness.”
