I summarized the flow of the argument this way:
We could spend multiple messages unpacking the doctrine of the Spirit, but I will resist that temptation for we will encounter His ministry nuymerous times to come in this discourse. But before we move on next time to the role of the Son of God, the second person of the Godhead, I do want you to see in verses 16-18, in addition to the identity of the Spirit as Helper, four other particulars that Jesus identifies about Him – His perpetuity, His priority, His exclusivity, and His intimacy. All of these contribute to the force of the advantage that comes to Jesus’ followers upon the loss of His presence in so short a time (John 16:7).
Praise God for the extraordinary help of the Holy Spirit in whom we find rest, are filled, and enjoy intimate relationship!
