Amish Grace. It is based on the true story of an Amish community that was devastated by a mass murder, and of how they forgave their killer. I highly recommend this movie, and rate it 3 Kleenex.
There was a point in the movie where the father of one of the slain little girls explains something that struck me hard. He says "God gave us our little girl. he has every right to call her back." We're so busy today saying how thankful we are for our friends and families, but how many look deeply into the fact that every second of every life is a gift that surpasses our wildest expectations. How many of us hold onto that thankfulness though loss and tragedy, like the gentleman portrayed in the movie.
I know that I, for one, and a pretty unthankful fellow.
