I heard this song for the first time the other day (because I'm always behind) and loved it immediately. If you've never heard it, take a listen. Mat Kearney wrote it about friends who went through Hurricane Katrina, but I think we can all insert ourselves into it in this: when everything else we have is threatened or blown away, we stand firm when our roots run deep in love. When events come along that shake away the temporal things that are shakeable, love remains. Love is unshakeable. Love never fails.
