"......He is the image of the invisible God, the firstborn over all creation. For by Him all things were created that are in heaven and that are on earth, visible and invisible, whether thrones or dominions or principalities or powers. All things were created through Him and for Him. And He is before all things, and in Him all things consist....." - Colossians 1:15-17

The Holy Spirit:
Much could be stated to describe the person and work of the Holy Spirit -- the third person of the Trinity [Triune God] The Nicene Creed spells out what Scripture tells, -- that He is co-equal with the Father and the Son. He is true God, along with the other 2 persons of the God-head.
The Holy Spirit possesses divine [holy] attributes. His work was creation [Psalm 33:6] and his continuing work is bringing souls to faith in Christ -- "regeneration," and the impartation of Christ's work of His atoning sacrifice to the believer. Titus 3:5 ; John 3:1-8
The Holy Spirit also is, the "Sanctifier," as it is His work to keep the believer in Christ, in the Faith. [Titus 3:5] Being the "Spirit of Truth," the Holy Spirit brings divine light into the believer's heart. [John 14:17 ; John 15:26] Christ also promised His immediate and future disciples, the Holy Spirit, who would be their "comforter" [helper] to be with them as they traverse this temporal life, as they deal with trials, afflictions and persecutions. John 16:13

Understanding the Triune God is not, 1 + 1 + 1 = 3 -- but rather, 1 X 1 X 1 = 1
