The Holy Spirit is God
Now the Lord is the Spirit, and where the Spirit of the Lord is, there is freedom. 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 Cor 3:17-18
The Holy Spirit dwells in Believers

2 Cor 1:22
For those who are led by the Spirit of God are the children of God.The Spirit you received does not make you slaves, so that you live in fear again; rather, the Spirit you received brought about your adoption to sonship. And by him we cry, “Abba, Father.”The Spirit himself testifies with our spirit that we are God’s children.
Romans 8:14-16

The Bible says: The sword of the Spirit is the Word of God
Take the helmet of salvation and the sword of the Spirit, which is the word of God.
Eph 6:17
Don't grieve the Holy Spirit
Do not grieve the Holy Spirit of God Eph 4:30. Do not quench the Spirit, 1Thess 5:19.
King David poured out His confession to God, after his sin with Bethsheba. he prayed to God: Don't take Your Holy Spirit from me (Psalm 51:11). Throughout the Bible we see people who grieve the Holy Spirit by their rebellion (Isaiah 63:10), lie against the Holy Spirit (Acts 3:5); resist the Holy Spirit (Acts 7:51). The warning is clear: Don't start with the Spirit and then finish by means of the flesh (Galatians 3:3).
Don't harden your heart, like the Pharisees: When the Pharisees accused Jesus of having a demon, and therefore be able to perform miracles, Jesus answered: "Anyone who speaks a word against the Son of Man will be forgiven, but anyone who speaks/blasphemes against the Holy Spirit will not be forgiven" (Matthew 12:32, Mark 3:29, Luke 12:10).
The Bible says: "Be filled with the Holy Spirit"
Do not get drunk on wine, which leads to debauchery. Instead, be filled with the Spirit, Ephesians 5:18
The Bible makes it clear in the book of Acts that:
Repent + Baptized + receive the gift of the Holy Spirit = a Christian
In Acts 2:38 Peter states: “Repent and be baptized, every one of you, in the name of Jesus Christ for the forgiveness of your sins. And you will receive the gift of the Holy Spirit."
John the baptist has said in several gospels: I baptize you 
with water, but He who comes, will baptize you with the Holy Spirit. (Matthew 3:11; Mark 1:8; Luke 3:16, Acts 1:5). This was fullfilled at Pentecost: All of them were filled with the Holy Spirit and began to speak in other tongues as the Spirit enabled them. Acts 2:4.
In the book of Acts, there are also some believers mentioned that did not receive the filling of the Spirit: “Did you receive the Holy Spirit when you believed?” They answered, “No, we have not even heard that there is a Holy Spirit.” Acts 19:2.
How do you get filled with the Holy Spirit? Pray and ask for it! The Bible says: "When they (Peter/John) arrived, they prayed for the new believers there that they might receive the Holy Spirit (Acts 8:15). God gives it generously: If you then, though you are evil, know how to give good gifts to your children, how much more will your Father in heaven give the Holy Spirit to those who ask him!” (Luke 11:13)
Walk by the Spirit, Live by the Spirit
So I say, walk by the Spirit, and you will not gratify the desires of the flesh. (Gal 5:16)
