The writing style of the Book of Mormon is sometimes awkward, but the spirit it carries and the principles it teaches are nothing less than eloquent. Nephi is indeed mighty in writing, because of the spirit of his message, for the Holy Ghost carrieth it unto the hearts of the children of men. His comment here is a product of his humility and is reminiscent of the words of Moroni, Lord, the Gentiles will mock at these things, because of our weakness in writing; for Lord thou hast made us mighty in word by faith, but thou hast not made us mighty in writing (Ether 12:23).
As we come to the end of Nephi’s record, it should be underscored that the mighty writings of Nephi contain almost every principle that will be dealt with in the rest of the Book of Mormon. In a sense, first and second Nephi are a condensed, “Readers Digest” version of the Book of Mormon. In the words of the Lord, the plates of Nephi…do throw greater views upon my gospel (DC 10:45). Those familiar with the Spirit of the Lord will recognize the words of Nephi as the words of Christ, if ye shall believe in Christ ye will believe in these words, for they are the words of Christ (v. 10). Furthermore, Nephi understood that the Lord was capable of making weak things become strong (Ether 12:27), for he said, the words which I have written in weakness will be make strong unto them (v. 4). Thus, the words of Nephi are mighty—they carry the Spirit of the Lord, they teach of Christ, they speak as the voice of one crying from the dust (v. 13), and will be used to judge us at the bar of the great Jehovah (v. 15).
