The "war chapters" in the Book of Mormon, particularly in the book of Alma, are less about military conflict and more about spiritual warfare and deliverance. They highlight how faith in God and righteousness lead to divine protection, even against overwhelming odds. These accounts serve as a guide for modern readers, illustrating that in times of spiritual or physical conflict, God's strength and guidance are available to those who remain faithful. The emphasis is on the eternal struggle between good and evil and the assurance that righteousness will ultimately prevail.
