Love is ... a heart of generosity
Love points us away from ourselves, so why not surprise someone who's not expecting it?
Easy for us smug marrieds of course, but what about everyone else? Widowed people looking at memories. Single people, who don't feel that's how they're meant to be. Teenagers feeling lonely and outside the boyfriend/girlfriend clique.
So maybe it's a day to surprise someone. To show them they ARE loved, whatever they think.
Luke 6: 27-36 certainly comes into play here.
Take a look at the video. And see what you can do.
