We are apt to complain, but remember: God’s infinite plan ordered [these trials]... The reason we do not see the wisdom of [the trial] is partly because being creatures we cannot fathom the wisdom of the Creator, and as sinful creatures we are blind and prejudiced. It is also partly because we forget the purpose they ultimately aim toward, and measure them by our own standards. It is also partly through our own pride, because we have such a high opinion of our own wisdom, which is foolishness indeed.
Samuel Willard
