The essential accompaniment of a genuine saving relationship with Jesus Christ is a life of holiness and obedience, attained by believers as they submit to the Holy Spirit, the third person of the Trinity. He was sent into the world by the Father and the Son to apply to mankind the saving work of Christ. He enlightens the minds of sinners, awakens in them a recognition of their need of a Savior, and regenerates them. At the point of salvation He permanently indwells every believer to become the source of assurance, strength and wisdom, and uniquely endows each believer with the gifts for the upbuilding of the body. The Holy Spirit guides believers in understanding and applying the Scripture. His power and control are appropriated by faith, making it possible for the believer to lead a life of Christ-like character and to bear fruit for the glory of the Father.
