I believe every book has a spirit to it. Not a literal spirit, but a feeling you get when you read it. When I read the Book of Mormon—which is another testament of Jesus Christ, a companion scripture to the Bible and a record of God’s dealings with the people who lived in the ancient Americas—I get a warm, peaceful feeling, like no matter what happens to me that day, I’ll be fine. As a lifelong member of The Church of Jesus Christ of Latter-day Saints—sometimes inadvertently called the Mormon Church because of the Book of Mormon—I have been reading this scripture my entire life. And the feelings of peace I get from reading the Book of Mormon increase the more I delve into these scriptures.
The Book of Mormon is the word of God. Nephi, a prophet in the ancient Americas whose history and revelations are found in the Book of Mormon, says in 2 Nephi 32:3, “Feast upon the words of Christ; … behold, the words of Christ will tell you all things what ye should do.” The warm and peaceful spirit I feel when I read the scriptures is the Holy Spirit, confirming to me the truthfulness of the words. How do I know this? Ether, another ancient American prophet whose writings are found in the Book of Mormon, says in Ether 4:11-12:
“He that believeth these things which I have spoken, him will I visit with the manifestations of my Spirit, and he shall know and bear record. For because of my Spirit he shall know that these things are true; for it persuadeth men to do good. And whatsoever thing persuadeth men to do good is of me; for good cometh of none save it be of me.”
The Book of Mormon is a ‘Safe Harbor’
Elder Jeffrey R. Holland, an Apostle of the Lord Jesus Christ, said:
“Love. Healing. Help. Hope. The power of Christ to counter all troubles in all times—including the end of times. That is the safe harbor God wants for us in personal or public days of despair. That is the message with which the Book of Mormon begins, and that is the message with which it ends, calling all to ‘come unto Christ, and be perfected in him’ (Moroni 10:32).” 
The Book of Mormon is a comforting friend and a safe harbor. Often when I read the verses inside, it is like they are speaking directly to me. I know the Book of Mormon is true, but not from a single, powerful spiritual witness. Of gaining a testimony—or a witness that the Book of Mormon is true—Elder Boyd K. Packer, the president of the Quorum of the Twelve Apostles (a governing body of The Church of Jesus Christ), said:
“My experience has been that a testimony does not burst upon us suddenly. Rather it grows, as Alma said, from a seed of faith. ‘It will strengthen your faith: for ye will say I know that this is a good seed; for behold it sprouteth and beginneth to grow’ (Alma 32:30). If you nourish it, it will grow; and if you do not nourish it, it will wither (see Alma 32:37–41). Do not be disappointed if you have read and reread and yet have not received a powerful witness. You may be somewhat like the disciples spoken of in the Book of Mormon who were filled with the power of God in great glory ‘and they knew it not’ (3 Ne. 9:20).
“Do the best you can. Think of this verse: ‘See that all these things are done in wisdom and order; for it is not requisite that a man should run faster than he has strength. And again, it is expedient that he should be diligent, that thereby he might win the prize; therefore, all things must be done in order’ (Mosiah 4:27).” 
This reminds me of a best friend. You don’t meet and become best friends in a day. You can become friends in a day, but true and lasting friendships develop over time. You share experiences, laughter, sorrow, confidences. Over time, the bonds deepen and you become best friends. The Book of Mormon is like a best friend for me. I can open the book in times of need and turn to verses that offer me comfort, insight and guidance. I have heard people say that they opened the scriptures to a random page and found answers to their prayers. While that has happened to me on occasion, more often I have found the answers I seek in the place where I am reading. It is a “safe harbor” where I can find answers, peace and guidance in the words of God.
Life is Hard, Handle with Prayer—and Reading the Book of Mormon
I can’t remember the exact phrase, but I love it: Life is hard, so handle with prayer. I added reading the Book of Mormon because prayer and reading this book of scripture has and continues to sustain me in good times and trials.
Elder Packer said:
“Life moves all too fast. When you feel weak, discouraged, depressed, or afraid, open the Book of Mormon and read. Do not let too much time pass before reading a verse, a thought, or a chapter.” 
I can always tell when I have slacked off my reading and praying. I am less able to handle the stress of kids, finances, housework and all of the other aspects of life. But when I delve into the scriptures, “feasting upon the words of Christ,” all things seem to fall into place. I have the patience I need with my kids. I am able to accomplish so much more and feel good about what I’ve done—and not stressed that I didn’t do enough.
As Elder Packer said, my testimony of the Book of Mormon didn’t come suddenly with a miraculous event. It has come slowly over time. Each time I read, I feel the spirit of the book and the Holy Spirit in the book. Like a best friend, I can always turn to the Book of Mormon to find the words my Heavenly Father wants me to hear—the answers to my questions, the peace I am seeking, the comfort that I need. And in doing so, my faith in my Heavenly Father increases, and I know that He knows me and loves me.
