Samuel Chadwick (1860-1932) was a Wesleyan Methodist who offered up straight-forward teaching to as many as would receive it. His teachings focus not on the theoretical expanses of what God may or may not do, but are instead centered on the Christian experience. However, he teaches only the experience which is clearly backed up by the Bible. Chadwick's definition of Pentecost is different than that of today's mainline Pentecostal churches. He is speaking of the classic Methodist teaching of entire sanctification, perfect love, or whatever else it may be called. However, this book is of great value to mainline Pentecostals, as these teachings are what helped birth the modern Pentecostal movement. What he has to say is desperately needed in the church today. There is no question why Chadwick's works have endured these many years past his death. He taught plainly from the living Word of God, and that word endures forever.
