The depiction of Jesus as the “Word” by John in his prologue has multifarious purposes. It can be argued that John’s chief purpose is to relate Jesus with the Old Testament theology surrounding the words from God as indicative of divine speech and ultimately to creation itself. Throughout his gospel, John consistently refers to Old Testament terminology so any discussion of the reasoning or sources for John’s usage of logos must begin there in order for this concept to be properly understood.
The Old Testament is replete with discussion of the Hebrew expression of word, dabar. Genesis equates this expression initially with the act of creation and later in a depiction of revelation and deliverance . The immediate nature by which the word of the Lord is employed throughout the Old Testament is consistently annotated in the narrative. Additionally, verses such as Psalm 107:20 describe God “sending forth His word” and the resulting action that took place once God spoke. All of these elements are subsumed within the concept of Jesus as the “Word.”
Carson lucidly outlines the connection between the Old Testament usage of word and John’s purpose by stating:
“In short, God’s Word in the Old Testament is his powerful self-expression in creation, revelation and salvation, and the personification of that Word makes it suitable for John to apply it as a title to God’s ultimate self-disclosure, the person of his own Son” .
