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. LewisWe are afraid that Heaven is a bribe, and that if we make it our goal we shall no longer be disinterested. It is not so. Heaven offers nothing that the mercenary soul can desire. It is safe to tell the pure in heart that they shall see God, for only the pure in heart want to. There are rewards that do not sully motives. A man's love for a woman is not mercenary because he wants to marry her, nor his love for poetry mercenary because he wants to read it, nor his love of exercise less disinterested because he wants to run and leap and walk. Love, by definition, seeks to enjoy its object.
C. S. LewisWe need not despair even in our worst, for our failures are forgiven. The only fatal thing is to sit down content with anything less than perfection.
C. S. Lewis
