"A Biblical Theology of the Holy Spirit: Luke-Acts" is the second volume in a four-volume set. This volume consists of a study of the Scriptures in Luke and Acts that refer to the Holy Spirit. The special, but not the only, emphasis of Luke is on the empowerment of the Spirit to speak prophetically and to witness. The empowering Spirit is poured out upon those who believe in Christ. As a result, believers become inspired and strong witnesses.
