 These words of grace are not just a sincere wish, but they are the power of God to do his work. Let's go back, however, to greeting cards for a moment. I have a number of greeting cards propped up in front of me. I have a birthday card, a get well card, a congratulations on your wedding card, and a sympathy card. Our local grocery store loves me for buying all of these, though they're wondering why I needed so many of them all at once.
