Different denominations and traditions of Christianity believe in forms divine grace. Roman Catholicism and Eastern Orthodoxy teach the complete importance of the free will to work together with grace. Reformed theology teaches the importance of grace by teaching that a person is completely incapable of self-redemption, but the grace of God overcomes even the unwilling heart. Arminianism believes in a synergistic view, while Lutheran and most other Protestant denominations teach justification by grace through faith alone.
