For many within the Church of Jesus Christ of Latter-day Saints, a strange relationship exists between the reader of scripture and the writings of the ancient Hebrew-poet Isaiah. Members of the church understand that Isaiah's writings are important; Christ himself approves the writings of Isaiah. Of the prophets in the Book of Mormon, none treasure or desire to share the words of Isaiah more than Nephi, son of Lehi.
Nephi truly was an inspired man that understood the importance of the scriptures, and knew Isaiah's important prophesies about the Savior of the world. While teaching his brothers about Christ, Nephi chose, out of all the scripture at his disposal, to teach from the writings of Isaiah. He did this "that [he] might more fully persuade them to believe in the Lord their Redeemer". To Nephi we can learn that Isaiah's writings have the ability to help us believe in Christ and build our faith in him. It is clear that the writings of Isaiah strengthened Nephi's testimony, for later in his record he states emphatically that "[Isaiah] verily saw my Redeemer, even as I have seen him."
Nephi, in continuing to talk about the coming of Christ says that he now writes "some of the words of Isaiah, that whoso of my people shall see these words may lift up their hearts and rejoice for all men. Now these are the words, and ye may liken them unto you and unto all men." The key phrase is to liken. The words of Isaiah must be experienced, not merely read. That is Nephi's exhortation to us, to come unto Christ by reading, applying, and then teaching the words of Isaiah. Nephi, and his great faith, came by this method and it will work in our lives just as it worked in his.
