Grace isn't legal, Its Divine
I have heard people say over and over...I want my rights! I deserve justice against the person who hurt me! Really? You do? You want justice? Thats just the line our enemy the devil wants to hear. Oh, you will get justice against the other person sooner or later, thats a given. But, in the enemies legalistic mind that will set you up for judgement and thats the arena that he operates in.
Grace, Gods grace, elivates us above judgement and out of that legalistic arena into a divine place where his love protects and nurtures us and nothing gets us there faster than forgiving the one(s) who hurt us.
