“In the beginning was the Word, and the Word was with God, and the Word was God. The same was in the beginning with God. All things were made by him; and without him was not any thing made that was made.” (John 1:1–3)

President Nelson taught “His title was the Word—spelled with a capital W. In the Greek language of the New Testament, that Word was Logos, or “Divine Expression.” It was another name for the Master. That terminology may seem strange, but it is so reasonable. We use words to convey our expression to others. So Jesus was the “Word” or “Expression” of his Father to the world.”

Elder Jeffrey R. Holland adds the following insights: “This metaphor for Jesus was expanded in John’s epistles, wherein he wrote, “Our hands have handled . . . the Word of life” (1 John 1:1) and “there are three that bear record in heaven, the Father, the Word, and the Holy Ghost” (1 John 5:7). John the Baptist appears to have used the title of Word for the Savior before any other did so (see JST, John 1:15–16; Doctrine and Covenants 93:6–18). It is instructive that Christ Himself used words as His principal tool in His role as “the Word, even the messenger of salvation” (Doctrine and Covenants 93:8). Even the Father acknowledged this distinctive element of the Savior’s ministry when He referred to Jesus as “the word of my power” (Hebrews 1:3).“
