I see the word undone meaning we realize we are not complete, we do not have the answers and when in front of Him we drop our arrogance. We are humbled by His greatness. Once we are undone, emptied, He fills us, but He can only fill what we empty out. Undone is a strong word, the synonyms are: unfinished, incomplete, unaccomplished, unfulfilled, unconcluded; When Christ died and rose again it was finished, completed, accomplished but only if we choose to believe. Only when we are undone can He make us whole.
