The Holy Spirit is co-equal with the Father and the Son, and indwells all true believers. His role is to bring glory to Jesus Christ, thus making Jesus Christ central in all things. The Spirit works to illuminate believers’ minds to grasp the truth of the Bible, producing in them his fruit, granting them his gifts and empowering them for service. He grants his gifts for the purpose of service, not self indulgence. Their use is determined – not by personal desire for fulfillment, or satisfaction – but by the principle of building the church. Not every gift of the Spirit is given to the church at every moment of its life, only those necessary for building Christ’s body.
The work of the Holy Spirit is necessary to make the death of Jesus effective in an individual’s life. The Spirit enables the sinner to repent and put their faith in Jesus Christ, so that salvation is entirely of God’s grace and not of human merit or works.
