Historian Vinson Synan has gathered sixty representative testimonies of the Spirit's power from the twentieth-century Pentecostal movement and beyond. Readers will discover the inspiring personal witnesses of such well-known and diverse figures as Amy Semple McPherson, Oral Roberts, Billy Graham, Jack Hayford, Agnes Ozman, Kenneth Hagin, Pope John Paul II, and many others. Synan has also included a few pre-twentieth-century testimonies, including John Wesley and Francis of Assisi. Readers and serious students will value these accounts of people receiving the baptism of the Holy Spirit; yielding to gifts such as tongues and prophecy; and receiving healings and other gifts of the Spirit.
