Let Us Raise Our Voice Of Warning - by President Henry B. Eyring, First Counselor in the First Presidency

Under the heading "Our Duty To Warn"

The article writes:

"The duty to warn our neighbor falls on all of us who have accepted the covenant of baptism. We 
are to talk with nonmember friends and relatives about the gospel. Our purpose is to invite them 
to be taught by the full-time missionaries, who are called and set apart to teach. When a person 
has chosen to accept our invitation to be taught, a “referral” of great promise has been created, 
one far more likely to enter the waters of baptism and then to remain faithful."

"As a member of the Church, you can expect that the full-time or the ward or branch missionaries 
will ask for the opportunity to help you make a list of people with whom you could share the gospel. 
The missionaries may suggest you think of relatives, neighbors, and acquaintances. They may ask 
you to set a date by which you will try to have the person or family prepared to be taught by the 
missionaries."

This is not the style of the New Testament Church. Every believer is a missionary and every
believer is called to preach or teach the gospel to friends, relatives, neighbors and
acquaintances.

"For us to know that the Book of Mormon is true, we must read it and make the choice found in 
Moroni: pray to know if it is true (see Moroni 10:3–5). When we have done that, we can testify 
from personal experience to our friends that they can make that choice and know the same truth."

While it takes some faith to come to know that the Bible is true, we also can rely on some
archaeological and geographical evidence.

Latter-day Saints do not have a testimony of archaeological and geographical evidence for 
the Book of Mormon because none exists.
