The power God gives people to save themselves, which he grants only after they have done everything they can do. “This grace is an enabling power that allows men and women to lay hold on eternal life and exaltation after they have expended their own best efforts” (LDS Bible Dictionary, p. 697). “… we know that it is by grace that we are saved, after all we can do” (2 Nephi 25:23).
Biblical Christianity teaches that grace is God’s unbelievable love for us. The preeminent example of this love is Jesus’ doing everything to save us. He kept the law perfectly for us. He died as payment for all our sins. It is by grace alone we are saved (Ephesians 2:8-9).
