The topic of the Holy Spirit sparks much interest these days, but also much confusion. Thanks to extra–biblical assertions about the Spirit’s person and work, ideas abound as to who the Spirit truly is, how He operates in time and space, and what precisely He does.

In this Crucial Questions booklet, 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.
