Why does the allegiance that radical terrorists give to their false cause exceed the allegiance that most Christians today give to Jesus Christ? In Insurgence, best-selling author Frank Viola presents a radical proposal for Christians. Namely, that we have lost the explosive, earthshaking gospel of the kingdom that Jesus, Paul, and the other apostles preached. Viola argues that we've lost this dynamic, titanic, living gospel and exchanged it for a gospel of religious duty or permissiveness and "easy believism." In today's politically charged era, Christians on the progressive left as well as the conservative right both equate their particular viewpoints with the kingdom of God. Viola challenges and dismantles these perspectives, offering a fresh and revolutionary look at the gospel of the kingdom. Viola writes with gripping power, challenging Christians to embrace an unparalleled allegiance to Jesus Christ and his kingdom. This high-octane message is being reclaimed today, launching a spiritual insurgence.
