Boyd K. Packer said,

We may foolishly bring unhappiness and trouble, even suffering upon ourselves. These are not always to be regarded as penalties imposed by a displeased Creator. They are part of the lessons of life, part of the test. Some are tested by poor health, some by a body that is deformed or homely. Others are tested by handsome and healthy bodies; some by the passion of youth; others by the erosions of age. Some suffer disappointment in marriage, family problems; others live in poverty and obscurity. Some (perhaps this is the hardest test) find ease and luxury. All are part of the test, and there is more equality in this testing than sometimes we suspect.

(Boyd K. Packer, CR, Oct. 1980, p. 29)
