Question: Give some specific references from Holy Scripture to the deity of the Holy Spirit.
Second, it is clear from that which all the prophets spoke through the Holy Spirit (1 Peter 1:12; 2 Peter 1:21).
10 As to this salvation, the prophets who prophesied of the grace that would come to you made careful searches and inquiries, 11 seeking to know what person or time the Spirit of Christ within them was indicating as He predicted the sufferings of Christ and the glories to follow. 12 It was revealed to them that they were not serving themselves, but you, in these things which now have been announced to you through those who preached the gospel to you by the Holy Spirit sent from heaven—things into which angels long to look. 1 Peter 1:10-12
19 So we have the prophetic word made more sure, to which you do well to pay attention as to a lamp shining in a dark place, until the day dawns and the morning star arises in your hearts. 20 But know this first of all, that no prophecy of Scripture is a matter of one’s own interpretation, 21 for no prophecy was ever made by an act of human will, but men moved by the Holy Spirit spoke from God. 2 Peter 1:19-21
As 1 Corinthians 2:10, 11 says, “God has revealed it to us through His Spirit. For the Spirit searches all things, even the deep things of God. For what man knows what is in a man except the spirit of the man which is in him. Even so no one knows what is in God, except the Spirit of God.” Also 1 John 4:13 “By this we know that He abides in us and we in Him, from the Spirit that He has given us.”
Thus Scripture speaks of these two as one and the same: God spoke through the prophets, and the Holy Spirit spoke through the prophets. (Hebrews 1:1; Acts 7:51, 52)
God, after He spoke long ago to the fathers in the prophets in many portions and in many ways, 2 in these last days has spoken to us in His Son, whom He appointed heir of all things, through whom also He made the world. Hebrews 1:1, 2
51 “You men who are stiff-necked and uncircumcised in heart and ears are always resisting the Holy Spirit; you are doing just as your fathers did. 52 Which one of the prophets did your fathers not persecute? They killed those who had previously announced the coming of the Righteous One, whose betrayers and murderers you have now become; Acts 7:51, 52
This is clearest of all in Hebrews 10:15-17
15 And the Holy Spirit also testifies to us; for after saying,
16 “This is the covenant that I will make with them
After those days, says the Lord:
I will put My laws upon their heart,
And on their mind I will write them,”
He then says,
17 “And their sins and their lawless deeds
I will remember no more.”
Here he says that the Holy Spirit spoke; in Jeremiah 31:31 it says: “The eternal God Jehovah spoke.” It follows, therefore, that the Holy Spirit is the true, eternal God. The Apostle Peter also mentions both to Ananias in Acts 5:3, 4 “You lied to the Holy Spirit . . . . You have not lied to men but to God.” In 1 Corinthians 6:19 the apostle demonstrates that our bodies are temples of God and thus the Holy Spirit dwells in us. From this and numerous other passages it is clear that the Holy Spirit is true God.
19 Or do you not know that your body is a temple of the Holy Spirit who is in you, whom you have from God, and that you are not your own? 20 For you have been bought with a price: therefore glorify God in your body. 1 Corinthians 6:19, 20
