John 16:14-15

The Spirit would glorify the Son by expounding Him, as the Son had glorified the Father by expounding Him. The Spirit would really be taking what the Father had given the Son and explaining its significance to the disciples, unpacking it. The Eleven are particularly in view. They were the individuals who were presently unable to understand further revelations, and they had been with Jesus since the beginning of His ministry (John 16:12; cf. John 14:26; John 15:27).

"The Spirit worked in the apostles’ minds so that they could perceive, understand, and teach about the Savior." [Note: Blum, p. 328.]

Many of the later New Testament writings expounded on the teachings of Jesus (e.g., Romans, Hebrews, James, 1 Peter, 1 John, Revelation; et al.).

Notice that it is not the Spirit’s function to attract attention to Himself or to promote Himself. As John the Baptist, His purpose is to make Jesus increase in prominence. This fact should make suspect any human attempt to glorify the Spirit above the Son. Such an emphasis is not in harmony with the Spirit’s purpose.

Jesus revealed that the Spirit would have a threefold ministry when He came. He would convict the world (John 16:8-11), enlighten the disciples (John 16:12-13), and glorify Jesus (John 16:14-15).
