The Savior told his Nephite disciples, "Whatsoever thing ye shall ask the Father in my name, which is good, in faith believing that ye shall receive, behold, it shall be done unto you." (Moroni 7:26) How well do you understand faith? It is one of the most powerful gifts of God, but many are not even sure what it is. In Living by the Power of Faith, Elder Gene R. Cook defines faith, describes its characteristics, and explains how to obtain faith, how to increase faith, and how to exercise faith to make your life richer and more productive. Elder Cook writes: "The purpose of this book is to help you learn what faith is, how to obtain it, and how to exercise it to cause great things to occur in your life and in the lives of others. This book is not intended to be just another reading experience. I hope that you will use this book to actually increase your faith and to help you improve your life and solve your problems." In teaching about faith, Elder Cook relates many stories from his own life and from the scriptures. At the end of each chapter he includes questions to help you ponder, understand, and apply the principles discusses. And he encourages you to study the scriptures and to pray in order to understand faith. He writes: "If you will pray intently as you read, the Lord will speak to you in your heart, for he, not this book, is our true teacher. He will open your mind as to how you can help a wayward child, a troubled friend, or an investigator with whom you are working. He will help you solve your problems at home, at church, at work, or at school. He will help you learn to live by the power of faith."
