“Grace” is the most important concept in the Bible, in Christianity, and in the world. The shorthand for grace is mercy, not merit.
Grace is getting what you don’t deserve and not getting what you do deserve. Grace is the opposite of karma. Grace is the love of God shown to the unlovely, the peace of God given to the restless, the unmerited favor of God. Grace is free sovereign favor to the ill-deserving. Grace is unconditional love toward a person who does not deserve it. Grace is love that cares and stoops and rescues. Grace is God reaching downward to people who are in rebellion against him. Grace is one-way love."
