Ezra Taft Benson taught,

“One of the trials of life is that we do not usually receive immediately the full blessing for righteousness or the full cursing for wickedness. That it will come is certain, but often times there is a waiting period that occurs, as was the case with Job and Joseph. In the meantime the wicked think they are getting away with something. The Book of Mormon teaches that the wicked “have joy in their works for a season, but by and by the end cometh, and they are hewn down and cast into the fire, from whence there is no return.”

(President Benson, CR, April 1988, p. 5)
