Pleasures

How sweet all at once it was for me to be rid of those fruitless joys which I had once feared to lose … ! You drove them from me, you who are the true, the sovereign joy. You drove them from me and took their place, you who are sweeter than all pleasure, though not to flesh and blood, you who outshine all light, yet are hidden deeper than any secret in our hearts, you who surpass all honor, though not in the eyes of men who see all honor in themselves. … O Lord my God, my Light, my Wealth, and my Salvation. Confessions, p181 (IX.1)

Provided the thing is in itself right, the more one likes it and the less one has to “try to be good,” the better. A perfect man would never act from sense of duty; he’d always want the right thing more than the wrong one. Duty is only a substitute for love (of God and of other people), like a crutch, which is a substitute for a leg. Most of us need the crutch at times; but of course it’s idiotic to use the crutch when our own legs (our own loves, tastes, habits, etc.) can do the journey on their own!

Lewis

God is most glorified in us when we are most satisfied in him. Which means they are finding that their desires, not just their decisions, really matter. The glory of God is at stake.
