We may look around and see all the beautiful buildings, houses, neighborhoods, trees, etc., and we may look very nice to everyone else ourselves too. Yet we fail to realize that we sin against the holy Lord God! When he looks down at us, he looks at our hearts. If they are not pure, he would see a sea of black stains, nothing beautiful about that. So take care of your hearts and souls first before the buildings, houses, neighborhood, trees, etc.
