>Free Grace theology is a Christian soteriological view which holds that the only condition of salvation is faith, excluding good works and perseverance, holding to eternal security. Free Grace advocates believe that good works are not necessary to merit (as with Pelagianism), to maintain (as with Arminians) or to prove (as with most Calvinists) salvation, but rather are part of discipleship and the basis for receiving eternal rewards (unlike in Hyper-Grace).^([1])^([2])^([3])^([4]) This soteriological view distinguishes between salvation and discipleship – the call to believe in Christ as Savior and to receive the gift of eternal life, and the call to follow Christ and become an obedient disciple, respectively.^([5]) Free Grace theologians emphasize the absolute freeness of salvation and the possibility of full assurance that is not grounded upon personal performance.^([6])^([7]) Thus, Free Grace theology allows for the salvation of an individual despite moral failings, although the disobedient Christian will face divine discipline.^([8]) Norman Geisler has divided this view into a moderate form and a more radical form. The moderate form being associated with Charles Ryrie and the strong form with Zane Hodges.^([9])
