“Fasting, coupled with mighty prayer, is powerful. It can fill our minds with the revelations of the Spirit. It can strengthen us against times of temptation. Fasting and prayer can help develop within us courage and confidence. It can strengthen our character and build self-restraint and discipline. Often when we fast, our righteous prayers and petitions have greater power. … Fasting in the proper spirit and in the Lord’s way will energize us spiritually, strengthen our self-discipline, fill our homes with peace, lighten our hearts with joy, fortify us against temptation, prepare us for times of adversity, and open the windows of heaven” (Wirthlin, “Law of the Fast,” 73–74).
