The seventh (a significant number) occurrence of the verb occurs in v. 14 when John describes how the Word “became” (ἐγένετο) flesh. This is the ultimate manifestation of God’s “creative” activity. The God who had been working from the outside was now on the inside; the Creator is now with his creation. In v. 14 Jesus is also described with a new title that is taken from the word’s root: “the unique Son” (μονογενής; repeated in v. 18). By means of this eighth use Jesus has become the pinnacle of creation, the center of human history and all created things. The ninth use of the verb in v. 15 reinforces Jesus’s place in history and the plan of God, making clear that Jesus “existed” not only before the time of the Baptist but before the creation of the world.
