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.
