I'm reminded of the story of the young soldier who was overseas. He was writing his girlfriend. He wanted to send her a telegram because he thought that would make more of an impression. So he gave the telegraph operator a message to send. The message was this: "I love you. I love you. I love you. John."
The telegraph operator said, "Son, for the same amount of money you can send one more word." So he amended his message and it read like this: "I love you. I love you. I love you. Cordially, John."
Many of us profess our love for God, "I love you, I love you, I love you," but when push comes to shove our devotion is more like "cordially" than it is love.
This widow put her money where her heart was. She gave all she had. And Jesus praised her.
