C. Peter Wagner was the Ambassadorial Apostle of Global Spheres, Inc. (GSI), an apostolic network providing activation and alignment for kingdom-minded leaders of the body of Christ. He traveled extensively throughout the world, helping to equip believers to minister in the areas of apostolic ministries, wealth, dominion, and reformation of society. Wagner considered this his "fourth career," which he began at the age of eighty. His first career was serving as a missionary to Bolivia, along with his wife, Doris; his second was teaching in the Fuller Seminary School of World Mission (now School of Intercultural Studies); and his third was founding and developing Global Harvest Ministries, which included the world prayer movement and Wagner University. WLI now has over twenty schools in the U.S. and twelve more in other nations. On October 21, 2016, Peter went home to be with the Lord.
