As the third person of the Trinity, the Spirit is co-equal with the Father and Son, and yet as a distinct person, the Holy Spirit is the one who regenerates us and guides us into all truth. He doesn’t speak on his own authority but relays the truth. The Holy Spirit is ever illuminating the work of the Son, bringing glory to Christ and declaring the Logos to the church.
The Bible is not silent regarding the person and work of the Holy Spirit! He appears on the opening page of Scripture (Genesis 1:2) and is seen throughout, most primarily in perfecting & sanctifying the believer.
The Person of the Holy Spirit
John 14:16-17 says, “16 And I will ask the Father, and he will give you another Helper, to be with you forever, 17 even the Spirit of truth, whom the world cannot receive, because it neither sees him nor knows him. You know him, for he dwells with you and will be in you.”
Notice with me that Jesus does not say the Spirit of truth is an “it” – but uses the personal pronouns “he” and “Him”. “You know Him, for he dwells with you, and will be in you.” We would not describe our spouses as “it” – unless we wanted to sleep on the couch. The Holy Spirit is not an impersonal wind, ghost, or force that you can channel or use like Luke Skywalker with enough concentration.
The Holy Spirit of God has knowledge (1 Cor 2:10-11), a will (1 Cor 12:11), a mind (Rom 8:27), He loves (Rom 15:30), reveals (Acts 13:2), intercedes (Romans 8:26), teaches (John 14:26), guides (Acts 16:6-7), can be grieved (Eph 4:30), insulted (Heb 10:29), lied to (Acts 5:3), and blasphemed (Matt 12:31-32). These can all only be referring to a Person.
You can’t grieve or lie to an “it”. You can’t sin against an impersonal thing. No one has ever sinned against their toaster by grabbing a bagel at Panera instead of at home – but countless men have sinned against their wives by committing adultery.
