Internal Beauty?

I was thinking about the whole "beauty comes from within" concept today. After reading this verse in I don't understand how that could happen.
Mark 7:21-23 (Amplified Bible)
For from within, [that is] out of the hearts of men, come base and wicked thoughts, sexual immorality, stealing, murder, adultery, coveting (a greedy desire to have more wealth), dangerous and destructive wickedness, deceit; unrestrained (indecent) conduct; an evil eye (envy), slander (evil speaking, malicious misrepresentation, abusiveness), pride (the sin of an uplifted heart against God and man), foolishness (folly, lack of sense, recklessness, thoughtlessness). All these evil [purposes and desires] come from within, and they make the man unclean and render him unhallowed.
Do we say that a flower is beautiful because of its "insides"? Or a sunset is beautiful because of what it means? No, these things are beautiful to the eye. Their beauty creates emotions in us. And when we see "beautiful people" they create emotions and feelings (not even saying that they are good emotions/feelings). I know the concept comes from how our view changes when we get to know people. So what is beauty? Maybe it is merely things that create those certain emotions and feelings in us. People see things differently. What is beautiful to me might not be beautiful to you. So is beauty in the eye of the beholder? Perhaps. We often hear men and women speak of their spouse as "the most beautiful man/woman". But they might not be the most beautiful to everyone else. But that doesn't mean they are not beautiful. So who are we to say who or what is or isn't beautiful? I can't, rightfully, say that someone is not beautiful.. because to someone they are beautiful. So I suppose what my point is (and not the point I was going to make at the start of this post) that everything and everyone is beautiful. We just need to shut up sometimes. But then we come to evil... what do we do about that? The only thing I can think is that we are made in the image of God... and He is beautiful. So to the eye, everything is beautiful. But sin covers us. Maybe that is where this "internal beauty" comes from. And everything that God makes is beautiful. Every storm, every insect, every organ, every creature, every hot Texas afternoon, EVERYTHING God makes is beautiful.
