The Law of the Fast

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. Testimonies grow. We mature spiritually and emotionally and sanctify our souls. Each time we fast, we gain a little more control over our worldly appetites and passions.
