John F. MacArthur
John MacArthur challenges the modern "free grace" movement by asserting that genuine saving faith demands a complete surrender to Jesus Christ as Lord, arguing that a faith without obedience is not a saving faith.
Saving faith inherently involves a radical turning from sin and a wholehearted submission to the sovereign authority of Jesus Christ.
While salvation is an unearned gift of grace, true justification triggers an immediate, miraculous regeneration that inevitably results in an observable life of obedience and good works.
Modern evangelistic methods often falsely assure unrepentant people of eternal security by reducing the gospel to a mere intellectual acceptance of historical facts.
