Faith is a direction of looking. And as soon as we are thankful our faith satellite is pointed in the right direction. If we are never thankful, we never see what God has for us anywhere. And the reason why God wants his children to be thankful is that thanksgiving makes us whole. We can also see that heart thanksgiving has a powerful effect.
Thankful people look radiant.
They are nice to have around. Grouchy, complaining people have a scowl on their face, and after a time it gets etched into the skin of their face. You can see across the street that they have a sour, crabby look. Women spend billions every year on cosmetics, but they forget that the quickest way to be attractive is to have a thankful heart. A young girl can have a gorgeous figure, but if she's a sour puss, she is as ugly as hell.
