Dr. R.C. Sproul cuts through the confusion by going back to the Bible. He establishes the biblical teaching on the Spirit's identity He is one of the three persons of the Godhead, along with the Father and Son then briefly sketches some of the most basic yet important roles the Spirit carries out. He shows that the Spirit gives new life to unbelievers, then sanctifies, strengthens, teaches, and anoints them for ministry. This booklet provides a basic understanding of the divine person on whom Christians' very lives depend.
