It will comfort us when we must wait in distress for the Savior's promised relief that He knows, from experience, how to heal and help us. The Book of Mormon gives us the certain assurance of His power to comfort. And faith in that power will give us patience as we pray and work and wait for help. He could have known how to succor us simply by revelation, but He chose to learn by His own personal experience.
