“Now some of you will say that the two are one and the same - happiness and joy - but this is not so. Happiness is a feeling. Happiness is fleeting, dependent on the moment, the circumstances, even the weather. Joy is transcendent, enduring, and, in the biblical context, is not an emotion. Joy is an attitude of the heart. Joy brings us peace, a refuge in the midst of troubles. God gives us joy through His Spirit. But the enemy tries to steal your joy and give you temporary happiness instead. Now, is there anything wrong with being happy? Nee, but it cannot last. So, you may wonder why I bring up the difference between these two - it is simple really. [...] marriage is sacred before the Lord, a decision for a lifetime, but too often I think young people look upon it as a source of happiness. Do not look at marriage this way. See it as a reservoir of joy, a deep, welling spring that endures the icy blast of temper, the bite of an angry word, the void of loneliness in a heart hungry for talk when there is no response. [...] Seek joy in each other, not happiness.”

“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.”

“Look for Joy: that's God's echo, and his footprint. Happiness . . . happiness and wittiness and cleverness do not count for much when the darkness falls. Joy is tougher.”

“Know that the happiness we feel when we bring joy to others is the greatest happiness in the world.”

“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.”

“Joy is distinctly a Christian word and a Christian thing. It is the reverse of happiness. Happiness is the result of what happens of an agreeable sort. Joy has its spring deep down inside. And that spring never runs dry, no matter what happens. Only Jesus gives that joy.”
