To delight in the good of all the universe, but not to delight in God, is like being glad that a candle is lit, but being indifferent to the rising sun. Apart from embracing God as our chief delight, we are (quite literally) infinitely parochial. - John Piper

This is . . . the difference between the joy of the hypocrite, and the joy of the true saint. The [hypocrite] rejoices in himself; self is the first foundation of his joy: the [true saint] rejoices in God. . . . True saints have their minds, in the first place, inexpressibly pleased and delighted with the sweet ideas of the glorious and amiable nature of the things of God. And this is the spring of all their delights, and the cream of all their pleasures. . . . But the dependence of the affections of hypocrites is in a contrary order: they first rejoice. . . that they are made so much of by God; and then on that ground, he seems in a sort, lovely to them.  - Jonathan Edwards
