The Holy Spirit is the Spirit of God, fully divine. He inspired holy men of old to write the Scriptures. Through illumination He enables men to understand truth. He exalts Christ. He convicts men of sin, of righteousness, and of judgment. He calls men to the Saviour, and effects regeneration. At the moment of regeneration He baptizes every believer into the Body of Christ. He cultivates Christian character, comforts believers, and bestows the spiritual gifts by which they serve God through His church. He seals the believer unto the day of final redemption. His presence in the Christian is the guarantee that God will bring the believer into the fullness of the stature of Christ. He enlightens and empowers the believer and the church in worship, evangelism, and service.

In this video, we explore the original meaning of the biblical concept of “spirit” and what it means that God’s Spirit is personally present in all of creation. Ultimately, the Spirit was revealed through Jesus and sent out into the lives of his followers to bring about the new creation.Holy Spirit, The Bible Project
The Holy Spirit is the third member of the Triune God and, as such, is fully God and fully personal.
One of the key areas of discussion with regard to the Holy Spirit has been his ontological status and his relationship within the Godhead to God the Father and God the Son. The baptismal formula of Matthew 28:19 contains an initial and succinct point of departure in this discussion. Here, God is described as “Father, Son, and Holy Spirit.” Since this baptismal formula implies a radical, wholehearted commitment to God, Christian authors in the New Testament and in the ancient church naturally included the Holy Spirit within the Godhead.
There are numerous texts in the New Testament as well as adumbrations in the Old Testament that speak implicitly of his deity and his doing only what God can do. The Spirit enables men and women to confess the true identity of Christ and worship him (1 Cor 12:3; Phil 3:3; Eph 2:18); he is the source of spiritual life (Gal 5:25; 6:8; Eph 1:13–14); he gives believers insight into divine mysteries, since he plumbs the depths of God (1 Cor 2:10); he gloriously transforms believers into the image of Christ and makes them the temple of God (2 Cor 3:18; 1 Cor 3:16). He is also described as eternal (Heb 9:14) and omnipresent (Ps 139:7); he is implicitly given the epithet “God” (Acts 5:3–4); and he is called by the divine title of “Lord” (2 Cor 3:17).
As a person, he can be grieved and lied unto (Isa 63:10; Eph 4:30; Acts 5:3–4); he leads believers (Gal 5:17); he enables prayer (Jude 20; Eph 6:18); he even prays (Rom 8:26–27). There are numerous passages in the New Testament Letters where the Holy Spirit is joined together with the Father and the Son as co-sources of the divine blessings that belong to believers in Christ (see 2 Cor 13:14; Titus 3:4–7; 1 Cor 12:4–6; Eph 4:4–6; 1 Pet 1:2; Jude 20–21). A number of statements by Christ in the farewell discourse (John 14–16) are especially rich with regard to the ontological status of the Holy Spirit. For example, the Spirit is being sent in the place of Jesus as “another Advocate” (John 14:16), but it is only through the Spirit’s presence in the disciples’ lives that Jesus, and the Father, are also present (John 14:23).
