I'm not sure God wants us to be happy. I think he wants us to love, and be loved. But we are like children, thinking our toys will make us happy and the whole world is our nursery. Something must drive us out of that nursery and into the lives of others, and that something is suffering.
C. S. LewisLove as distinct from "being in love" is not merely a feeling. It is a deep unity, maintained by the will and deliberately strengthened by habit.
C. S. LewisIf nothing in this world satisfies me, perhaps it is because I was made for another world.
C. S. LewisAs Venus within Eros does not really aim at pleasure, so Eros does not aim at happiness. We may think he does, but when he is brought to the test it proves otherwise... For it is the very mark of Eros that when he is in us we had rather share unhappiness with the Beloved than be happy on any other terms.
C. S. LewisBut the great thing to remember is that, though our feelings come and go, His love for us does not. It is not wearied by our sins, or our indifference; and, therefore, it is quite relentless in its determination that we shall be cured of those sins, at whatever cost to us, at whatever cost to Him.
C. S. Lewis
