Is there not wisdom in his giving us trials that we might rise above them, responsibilities that we might achieve, work to harden our muscles, sorrows to try our souls? Are we not exposed to temptations to test our strength, sickness that we might learn patience, death that we might be immortalized and glorified?
If all the sick for whom we pray were healed, if all the righteous were protected and the wicked destroyed, the whole program of the Father would be annulled and the basic principle of the gospel, free agency, would be ended. No man would have to live by faith." -Spencer W. Kimball
