These ads for Direct TV were very effective. You wanted to see how they would end. "Don't be that guy" was the theme. Psalm 78 is has that same theme...."Don't be those guys!" It tells the story of Israel and their bad choices, lack of trust and the outcome. Don't be those guys. It has the same humor and sad outcome. I thought about this ad as I read the chapter this morning. How often we are that guy!
