" But another theme, another refrain, is equally marked, and this one is missed by the cynic. This is the refrain which sings the great gift of God. Under the sun, vanity is God’s scepter (5:18; 8:15; 9:9). For those who fear Him, He gives the gift of being able to actually enjoy this great big marching band of futility—the tubas of vanity bringing up the rear. God gives to a wise man the gift of watching, with a pious and grateful chuckle, one damn thing after another. All things considered, the furious activity of this world is about as meaningful as the half-time frenzy at the Super Bowl. But a wise man can be there and enjoy himself. This is the gift of God. The wise will notice how this point is hammered home, throughout the book, again and again. Slowly it dawns on a man that this is really a book of profound . . . optimism. "
