Grace Upon Grace

We are all sinners; instilled in our being from the fall of Adam in the Garden of Eden. There's nothing we, ourselves, can do to redeem ourselves. God loves us lashishly; so much so that he sacrificed his only Son, not only to pay for our sins (grace) but to make us worth to be called "Sons and Daughters" of the King. Now THAT, is "grace upon grace" like the story of Mephibosheth in 2 Samuel.
