When I think of God's grace, I think of this passage:
Romans 5:6-11 (KJV)
6For when we were yet without strength, in due time Christ died for the ungodly.
7For scarcely for a righteous man will one die: yet peradventure for a good man some would even dare to die.
8But God commendeth his love toward us, in that, while we were yet sinners, Christ died for us.
9Much more then, being now justified by his blood, we shall be saved from wrath through him.
10For if, when we were enemies, we were reconciled to God by the death of his Son, much more, being reconciled, we shall be saved by his life.
11And not only
so, but we also joy in God through our Lord Jesus Christ, by whom we have now received the atonement.
