Final answer:
John's Gospel begins with an allusion to Genesis 1:1, highlighting Jesus's preexistence and divine role in creation.
Step-by-step explanation:
John's Gospel begins with an allusion to the Old Testament passage from the book of Genesis. Specifically, it references the very beginning of the Bible, where the creation narrative is told. John's Gospel starts with, "In the beginning was the Word, and the Word was with God, and the Word was God." This mirrors Genesis 1:1 which states, "In the beginning, God created the heavens and the earth." The allusion establishes that Jesus (the Word) was present at the creation of the world and is co-eternal with God, echoing the themes of preexistence and divine participation in creation.
