Who the Holy Spirit is
The Holy Spirit is not a force or a feeling. He is a Person, fully God with the Father and the Son, and Jesus promised Him to everyone who follows Him. Older translations like the King James call Him the Holy Ghost; it is the same Spirit.
On the night before He died, Jesus told His friends He was leaving, and that it was good for them, because the Spirit would come. These are some of the clearest holy spirit scriptures in the Bible:
And I will ask the Father, and he will give you another advocate to help you and be with you forever — the Spirit of truth. The world cannot accept him, because it neither sees him nor knows him. But you know him, for he lives with you and will be in you.
John 14:16–17 · NIV
Another advocate: someone called alongside to help, exactly as Jesus had been. And not for a season. Forever.
But the Advocate, the Holy Spirit, whom the Father will send in my name, will teach you all things and will remind you of everything I have said to you.
John 14:26 · NIV
Teacher and reminder. When a verse comes back to you at the moment you need it, that is often the Spirit at work.
1 Corinthians 3:16You yourselves are God’s temple, and God’s Spirit lives among you.
