Free Grace theology is a soteriological view within Protestantism teaching that everyone receives eternal life the moment they believe in Jesus Christ as their personal Savior and Lord. "Lord" refers to the belief that Jesus is the Son of God and therefore able to be their "Savior". The view distinguishes between the "call to believe" in Christ as a Savior and receiving the gift of eternal life, and the "call to follow" Christ and become obedient disciples, meaning that the subsequent behavior of the justified believer is relevant in terms of the Lord's approval and rewards, but sanctification is optional.
