The Glorified Lord Christ lived with them in His body until He rose to Heaven then promised them the Holy Spirit to stay with them forever, the Spirit of truth, the Comforter. So what should we know about the Holy Spirit?

The Holy Spirit is God’s Spirit, therefore it existed since ever. We read about it in the first verses of the Genesis Book. The divine response says: “In the beginning God created the heavens and the earth. The earth was without form, and void; and darkness was on the face of the deep. And the Spirit of God was hovering over the face of the waters.” (Gn 1:1, 2)..
