John moves on to again make note of John’s testimony to Jesus in verse 15, and finally makes it plain that he is speaking of Jesus Christ by using that phrase for the first time in verse 17. But before he closes his prologue, John uses what is often called the “bookends” technique. He provides a closing statement that sums up and repeats, in a different form, what he said in his introduction. And this is found in the final verse of the prologue, verse 18.
