The Bible and the Book of Mormon

“And if ye shall believe in Christ ye will believe in these words, for they are the words of Christ, ... and they teach all men that they should do good.”

-2 Nephi 33:10

The Book of Mormon and the Bible Support Each Other

Like two eyewitnesses strengthen an argument in court, the Book of Mormon and the Bible both testify of Christ.

Some people think that because we read the Book of Mormon, we don't read the Bible. That's just not true. It's like saying that we don't eat oranges because we eat apples. Both are good fruit! The Book of Mormon is not a replacement for the Bible. In fact, because the Book of Mormon and the Bible both contain the gospel of Jesus Christ as it was revealed to different civilizations, studying them together can clarify some concepts that are difficult to understand. The Book of Mormon tells us to read the Bible and affirms that its message is true (Mormon 7:8-10). And in the Bible, Jesus told His apostles,  
“Other sheep I have, which are not of this fold: them

also I must bring, and they shall hear my voice; and there shall be one fold, and one shepherd” (John 10:16). Christ visited these “other sheep” in the Americas after He was resurrected, teaching the same message to the Nephites that He taught to the people of Israel. The Book of Mormon makes it clear that Jesus Christ's message and His atonement are not for one group of people at one time. They are for everyone, everywhere, from the beginning of the earth to the end. Having the Book of Mormon as another testament of Jesus Christ reminds us that He is mindful of every one of us.
