“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.”

“Sorrow fully accepted brings its own gifts. For there is alchemy in sorrow. It can be transmitted into wisdom, which, if it does not bring joy, can yet bring happiness.”

“...living the same sorrows three times was a suffering, but it was a suffering to relive even the same joys. The joy of life is born from feeling, whether it be joy or grief, always of short duration, and woe to those who know they will enjoy eternal bliss.”

“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.”

“Participate joyfully in the sorrows of the world. We cannot cure the world of sorrows, but we can choose to live in joy.”

“That sorrow which is the harbinger of joy is preferable to the joy which is followed by sorrow.”
