I am undone is not a bad place to be. "God will never do anything with us till he has first of all undone us." (Spurgeon)
So I said: “Woe is me, for I am undone! Because I am a man of unclean lips... For my eyes have seen the King, The Lord of hosts.” - Isaiah the Prophet of God
To be “undone” in Christ does not mean failure, but instead reflects an always GROWING in Christ’s Image while being UNDONE to self.
