“How can I explain to my friends why we need the Book of Mormon?” New Era, Feb. 2020, 45.
We believe that the Book of Mormon was prepared by the Lord for our day and is necessary for us. Here are a few reasons why (as explained by President Russell M. Nelson):
It contains the answers to life’s most compelling questions.
It teaches the doctrine of Christ.
It expands and clarifies many of the “plain and precious” truths from the Bible that were lost (see 1 Nephi 13:29–33).
It provides the fullest and most authoritative understanding of the Atonement of Jesus Christ to be found anywhere.
It teaches us about the gathering of scattered Israel.
It exposes the tactics of the adversary (see 2 Nephi 26–33).
It dispels false religious traditions.
It abolishes forever the false concepts that revelation ended with the Bible and that the heavens are sealed today.
