New Defender's Study Bible Notes
16:8 when he. Note that the Holy Spirit is “He,” not “it.” He is the third Person of the triune Godhead, not a spiritual influence of some kind. The Greek word (pneuma) is neuter, sometimes translated also as “wind” or “breath.” Consequently, the pronoun “it” has occasionally been used when referring to the Holy Spirit, even in the King James translation. This should be corrected to “He” or “Him” whenever that is the meaning. It is correctly translated thus in every case here in the Lord’s message in John 14, 15 and 16.
16:8 reprove. Here “reprove” has the thrust of “convict” or “bring under conviction.” Thus, in addition to His personal ministry to each believer, the Holy Spirit also has a ministry to the ungodly world at large, speaking to each unbeliever regarding his need of salvation, and restraining general wickedness (see note on II Thessalonians 2:6-7).
