Because as you know, we have to live our lives by EVERY THING mentioned in the Bible and nowhere in the Bible does it mention disowning DirecTV to go to Dish or trading my Honda in for a Chevrolet. What would God think of me doing that?
You are incorrect, it is never said that we can only live with things mentioned in the Bible. We are to obey God's word though. If Directv leads you to sin then disconnect it.
