God's face shining through
This reminds me of a testimony I'd read in a book about angels appearing on earth and other such miracles.
In one there was a criminal who testified that he was going to attack, rob, and otherwise harm a woman who had been walking alone to her car -- except that she *looked* at him, and that for just a moment he thought he saw her face disappear and "the face of Jesus" appear in its place. He would have been terrified but the face - smiled - at him. And I rather suspect that was the moment this man laid aside most of his criminal ways (though the book didn't say).
Isn't it interesting that this man - clearly not on a path "with God" - knew Jesus' face when he saw it? And what a wonderful testimony of Christ's compassion that He would look upon this wicked man and give a smile of pardon to him!
Human beings are the *only* "animal" on the planet who show our teeth as anything other than a gesture of threat. One of the (many) things that sets us uniquely apart from the animal kingdom is that ability to smile. Even more interesting is that animals that would normally respond to showing teeth as a hostile gesture, respond to *human* smiling as a comforting thing (just go smile at your dog and you'll see what I mean).
Smiles are *universally* understood across all races, genders, and cultures. We even universally "get" when a smile is being used as a joke, or in sarcasm, or as a flirt etc. There's a whole language just in our faces.
So remember -- we are made in God's image -- let us be certain to keep our own faces in a pose that glorifies His Love.
I pray for the day that God's Christians are so deeply in communion with Him that everyone else will look upon our faces and see only Jesus too.
