Quote from : The God Who Weeps: How Mormonism Makes Sense of Life Book

In the Garden story, good and evil are found on the same tree, not in separate orchards. Good and evil give meaning and definition to each other. If God, like us, is susceptible to immense pain, He is, like us, the greater in His capacity for happiness. The presence of such pain serves the larger purpose of God's master plan, which is to maximize the capacity for joy, or in other words, "to bring to pass the immortality and eternal life of man." He can no more foster those ends in the absence of suffering and evil than one could find the traction to run or the breath to sing in the vacuum of space. God does not instigate pain or suffering, but He can weave it into His purposes. "God's power rests not on totalizing omnipotence, but on His ability to alchemize suffering, tragedy, and loss into wisdom, understanding, and joy.
