WARNING: Religion has been known to cause blindness in Californian mice!

I just read the story of the man born blind (John 9). Jesus heals him and causes a stink with the religious leaders (Pharisees). Why would they be upset about this? Because Jesus healed the man on the Sabbath, the Jewish day of rest. 

• “Remember the Sabbath day by keeping it holy. Six days you shall labor and do all your work, but the seventh day is a sabbath to the LORD your God. On it you shall not do any work..." Exodus 20:8-11

So it is true that God told the Jews not to work on the Sabbath. But did He really mean they couldn't do good deeds? Obviously not, since Jesus IS God and here He is doing a good deed on the Sabbath. So the religious leaders had been blinded by their own religion to the truth of God!

How many car accidents happen because people don't realize they have a blind spot in their vision? How many religious accidents have happened because people don't realize they have a blind spot in their vision?

If my religion has given me a blind spot do I even I know it?
