Our main task is to declare the gospel and do it effectively. We are not obligated to answer every objection. Every man eventually is backed up to the wall of faith, and there he must make his stand. The Book of Mormon is to be used "for a standard unto [all] people, which are of the house of Israel," the Lord says, and its words "shall hiss forth unto the ends of the earth." We, the members of the Church, and particularly the missionaries, have to be the "hissers," or the tellers and testifiers, of the Book of Mormon unto the ends of the earth. The Book of Mormon is the great standard we are to use. The Book of Mormon is the great finder of the golden contact. It does not contain things which are "pleasing unto the world." It is a great sieve.
