We extend heartfelt feelings of gratitude to each of you, brothers and sisters. Throughout the world, your examples of service and compassion are receiving a great deal of attention. At the same time, many people are wondering about this Church’s history and doctrines. Among those questioners are some who choose to cast aspersions at the Book of Mormon.
The Bible and the Book of Mormon are both witnesses of Jesus Christ. They teach that He is the Son of God, that He lived an exemplary life, that He atoned for all mankind, that He died upon the cross and rose again as the resurrected Lord. They teach that He is the Savior of the world.
Scriptural witnesses authenticate each other. This concept was explained long ago when a prophet wrote that the Book of Mormon was “written for the intent that ye may believe [the Bible]; and if ye believe [the Bible] ye will believe [the Book of Mormon] also.” Each book refers to the other. Each book stands as evidence that God lives and speaks to His children by revelation to His prophets.
Love for the Book of Mormon expands one’s love for the Bible and vice versa. Scriptures of the Restoration do not compete with the Bible; they complement the Bible. We are indebted to martyrs who gave their lives so that we could have the Bible. It establishes the everlasting nature of the gospel and of the plan of happiness. The Book of Mormon restores and underscores biblical doctrines such as tithing, the temple, the Sabbath day, and the priesthood.
An angel proclaimed that the Book of Mormon shall establish the truth of the Bible. He also revealed that writings in the Bible available in our day are not as complete as they were when originally written by prophets and apostles. He declared that the Book of Mormon shall restore plain and precious things taken away from the Bible.
A prophecy in the Book of Mormon warned that some people would object to the notion of additional scriptures. To those who think they “need no more Bible,” consider this God-given counsel:
Know ye not that there are more nations than one? Know ye not that I, the Lord your God, . . . created all men, . . . and that I rule in the heavens above and in the earth beneath; and I bring forth my word unto the children of men, yea, even upon all the nations of the earth? . . . Know ye not that the testimony of two nations is a witness unto you that I am God, that I remember one nation like unto another? Wherefore, I speak the same words unto one nation like unto another. And . . . the testimony of the two nations shall run together also.
The scriptural story of Jesus Christ is indeed a two-hemisphere story. While Mary and Joseph in the East were making preparations for the holy child’s birth in Bethlehem, Nephi in the West was being taught by the premortal Messiah. To Nephi the Lord said, “Be of good cheer; . . . on the morrow come I into the world, to show unto the world that I will fulfil all that which I have caused to be spoken by the mouth of my holy prophets.”To doubters of that second witness—the Book of Mormon—the Lord issued a warning:
Because you have treated lightly the things you have received . . . [you] shall remain under . . . condemnation until [you] repent and remember . . . the Book of Mormon and the former commandments which I have given . . . , [the Bible, and] . . . do according to that which I have written.
