In his first major book, Ed Dufrense, an internationally known preacher and teacher, issues a no-holds-barred call to the Charismatic, Pentecostal, and Faith Movements - a ringing warning to catch the new wave of God's Spirit or be left behind. In Fresh Oil From Heaven, Dr. Dufrense traces the work of the Holy Spirit in this century to major revivals every 40 years, punctuated by fresh moves every 20 years.
