A Person! The Holy Spirit is a person. In the Book of John, the Holy Spirit is doing something only a person could do: teaching (14:26), bearing witness (15:26), convicting, guiding, speaking, etc. (16:8, 13). The apostles knew Him as a person, Acts 15:28, “For it seemed good to the Holy Spirit and to us…”. So it is obvious the Scriptures do indeed teach that the Holy Spirit is a person with thought and action.
A Divine Person! There was a man named Ananias who sold some land. He laid some of the proceeds at the apostle’s feet but telling them it was the total amount. Peter knew this to be a lie, saying to Ananias, “You have lied to the Holy Spirit,” in the next verse, also saying, “You have lied to God,” Acts 5:1-4. The Holy Spirit is “God” just as the Father is “God.” The Holy Spirit is known as the eternal Spirit (only Deity is infinite), Hebrews 9:14. As the Father searches the heart, Romans 8:27, and Jesus searches the heart, Revelation 2:23, the Holy Spirit also searches all things, even the deep things of God, 1 Corinthians 2:10. Believers are baptized into the Father, the Son, and the Holy Spirit; all three are Deity, Matthew 28:19.
A Divine Role! The Holy Spirit plays a divine role. There’s creation, Genesis 1:2; Preaching, Acts 16:6-7; Evangelism, Acts 14:27 [The word “God” is used in the verse but note that in Acts 16:6-7, the Holy Spirit directs the apostle in preaching]. Even Jesus’ birth was possible by the Holy Spirit, Matthew 1:18. Also, Jesus’ baptism involved the Holy Spirit, Matthew 3:13-17.
According to the Book! The Holy Spirit is a divine being, just as the Father and Jesus are Deity. Finally, it’s worth knowing that the words ‘Holy Spirit’ is found in over 120 verses of the NLT of the Bible.
