The Holy Spirit is the divine “Third Person of the Trinity” and is called God.
Then Peter said, “Ananias, how is it that Satan has so filled your heart that you have lied to the Holy Spirit and have kept for yourself some of the money you received for the land? Didn’t it belong to you before it was sold? And after it was sold, wasn’t the money at your disposal? What made you think of doing such a thing? You have not lied just to human beings but to God.” - Acts 5:3-4 (NIV)
...these are the things God has revealed to us by his Spirit. The Spirit searches all things, even the deep things of God. - 1 Corinthians 2:10 (NIV)

And we all, who with unveiled faces contemplate the Lord’s glory, are being transformed into his image with ever-increasing glory, which comes from the Lord, who is the Spirit. - 2 Corinthians 3:18 (NIV)

As for you, the anointing you received from him remains in you, and you do not need anyone to teach you. But as his anointing teaches you about all things and as that anointing is real, not counterfeit—just as it has taught you, remain in him. - 1 John 2:27 (NIV)
He has a divine name (“Lord,” 2 Cor. 3:18), divine attributes (“eternal,” Heb. 9:14; and “holy,” Eph. 4:30), emotion (“grief” Eph. 4:30) and can be mistreated as a sacred Person (“blasphemed,” Luke 12:10).
The Holy Spirit speaks through the Word of God.
Take the helmet of salvation and the sword of the Spirit, which is the word of God. - Ephesians 6:17 (NIV)
Be prepared. You’re up against far more than you can handle on your own. Take all the help you can get, every weapon God has issued, so that when it’s all over but the shouting you’ll still be on your feet. Truth, righteousness, peace, faith, and salvation are more than words. Learn how to apply them. You’ll need them throughout your life. God’s Word is an indispensable weapon. In the same way, prayer is essential in this ongoing warfare. Pray hard and long. Pray for your brothers and sisters. Keep your eyes open. Keep each other’s spirits up so that no one falls behind or drops out. - Ephesians 6:17 (MESSAGE)
The Holy Spirit speaks to individuals.

He will glorify me because it is from me that he will receive what he will make known to you. All that belongs to the Father is mine. That is why I said the Spirit will receive from me what he will make known to you. - John 16:13-15 (NIV)

Above all, you must understand that no prophecy of Scripture came about by the prophet’s own interpretation of things. For prophecy never had its origin in the human will, but prophets, though human, spoke from God as they were carried along by the Holy Spirit. - 2 Peter 1:20-21 (NIV)

But when he, the Spirit of truth, comes, he will guide you into all the truth. He will not speak on his own; he will speak only what he hears, and he will tell you what is yet to come. - John 16:13 (NIV)
He speaks to us through the Gifts of the Spirit.
1 Co 12-14
