At the end of chapter 15, we get the same kind of emphasis, verse 26: “When the Helper comes, whom I will send to you from the Father.” Again, the Spirit of truth, emphasizing that this primary ministry is to provide the truth. “He will testify about Me. That’s what He is going to do, testify about Me. So He’s going to teach you. He’s going to bring to remembrance everything I said, and He’s going to teach you about Me.” That really sums up what the Holy Spirit does in revealing Scripture. Scripture is divine teaching. It is the record of all that Jesus did and said, and it is all the epistles and letters that tell us what His life and ministry meant: “All the things that relate to Me.” That’s the ministry of the Holy Spirit. The Holy Spirit: God’s Prosecutor (John 16:8–11)
Do not marvel that I said to you, 'You must be born again.' (John 3:7)
