What does it mean to be filled with the Holy Spirit and is this something that is true of all Christians? What kind of person does God delight to use in the work of his kingdom? What is revival?

These are just some of the issues Geoff Thomas deals with in this popular, thought-provoking, and soul-stirring study of Philip the Evangelist and the great Samaritan awakening, recorded in Acts chapter 8.
