When Jesus tells God the Father that he has revealed God’s name to the disciples (John 17:6), he isn’t talking about telling the disciples what God’s name was. They could read their Old Testament and see that in thousands of places (e.g., Exod 3:1–14). Revealing God’s name to them meant showing them who God was and what he was like. He did that by living among them as a man. Jesus was God among them. He was the incarnation of God’s essence (Heb 1:3).
