"Happiness is a consequence of good things happening around us; it is superficial. But Joy comes from inside, from knowing that God has not forsaken us and that He does indeed love us. That Joy can come from no one but the Holy Spirit." Ruth Senter
Joy, must be sharply distinguished both from Happiness and Pleasure. Joy has indeed one characteristic, and one only, in common with them; the fact that anyone who has experienced it will want it again...I doubt whether anyone who has tasted it would ever, if both were in his power, exchange it for all the pleasures in the world. But Joy is never in our power and pleasure often is." C.S. Lewis
