The phrase “plain and precious” appears nine times in a span of fifteen verses. Taking away plain and precious things perverts the correct understanding of the nature of God and causes people to stumble doctrinally. Biblical examples include “No man hath seen God at any time” (John 1:18) and “God is a spirit” (John 4:24).
To help remedy these losses and misunderstandings, God has brought forth “other books,” and “these last records [Book of Mormon, Doctrine and Covenants, Pearl of Great Price, and the Joseph Smith Translation of the Bible] … shall establish the truth of the first [the Bible], … and shall make known the plain and precious things which have been taken away.” For example, latter-day scripture has restored the truth that “the Lamb of God is the Son of the Eternal Father, and the Savior of the world; and that all men must come unto him, or they cannot be saved.”
The prophecy “the words of the Lamb shall be made known in the [Book of Mormon], as well as in the [Bible]; wherefore they both shall be established in one” is certainly accomplished in the publication of the Book of Mormon, the Doctrine and Covenants, the Pearl of Great Price, and the Latter-day Saint edition of the King James Bible. They have become literally one in our hand in testifying of the divine Sonship of Jesus Christ (see 2 Nephi 3:12).
We see again in this passage how the term Gentile is used. It can refer to anyone, even an Israelite, who is not of the house of Judah, or it can refer to those raised in a non-Israelite, or Gentile, culture.
