The theological introduction that the Apostle John provides to his account of the life, death, and resurrection of Messiah (John 1:1–18) is as deep as it is lofty, as commanding as it is inviting, and as mysterious as it is familiar. It draws readers close, not only with its infinitely-interesting Subject but with the reverent way it explains and extols him. Simply stated, this passage of Scripture is all about the Word, the person who was with God in eternity and is God eternally. It’s all about he who is the origin of all life and the source of all light. It’s all about, as verse 17 makes explicit, Jesus Christ. And the five concluding verses of this inspired prologue summarize and celebrate three specific things about him: who he is (God himself), what he did (took on humanity), and why he did it (that humanity may know God).
