The Holy Spirit, indwells in the believer to make the Trinity alive and personal to the believer. The Holy Spirit, as the Third person of the Trinity is absolutely eternal (Gen 1:2), was involved actively in Creation, and in all of mankind’s interaction including in Jesus’ resurrection (Rom 8:11). Scripturally, The Holy Spirit is supported in omniscience, equally deified with the Father and the Son (Matt 28:19) and is just as intimately involved in the ultimate revelation. The Holy Spirit is not distant, nor detached from the life of the believer.
Scripture is the divine revelation, God-breathed through the Spirit, and thus stands as one of the greatest gifts of the Spirit. (2 Tim 3:16). The Holy Spirit continues through the believer to illuminate the divine nature of the Bible and acts as our ultimate witness for the confidence to know Scripture as the Word of God.
The Holy Spirit is responsible for the sanctification of the believer through the gift of discernment and conviction (John 16:8-11). He is also the provider for regeneration and the bridge for our baptism to unlock the door to salvation (John 3:5-8). The “new man” (Eph 4:24) is truly the manifestation of the Spirit in the believer. Further, the role of the Holy Spirit is that of teacher (John 14:26), comforter/advocate/counselor (John 14:16), speaker (Mark 13:11), and witness (Rom 8:16); active in administration (Acts 6:1-3), conversion (Acts 19:2) and intercession (Rom 8:26).
Similar to the seemingly contrary concept of Jesus as fully God and fully man, the Spirit is not a “ghost”, nor a force, but rather a person of whom is fully God. He maintains similar functions as Jesus did and possess qualities similar to a human concept of personality. However it is important to maintain that the Spirit is in direct opposition to that of the flesh.
In terms of the view of the gifts of the Holy Spirit, I maintain that all believers are granted gifts and are not only encouraged to but also responsible for using them to minister. All spiritual gifts have existed at some point and because time is more of a human notion than it is of God, they certainly can still all exist because they like everything else in creation, are subject to existence by the will of their Creator. Believers are meant to be transformed into the image of Christ through the process of sanctification. Whether for some that includes the gift of tongues, prophecy or otherwise, only the Spirit would know. While recognizing the value and Biblical support for both Cessationists and Continuatists, because Jesus states that we will be able to do even greater than He (John 14:12), I cannot determine any Biblical reason to insist that certain gifts have or have not ceased.
