I used to believe that taking the lord's name in vain was praying for silly or selfish things. When you prayed then God or Jesus had to stop whatever they were doing to listen to your prayer. This was a waste of their time which they could be doing more important things. This was a real problem because there are so many people in the world. Also religious people hurt Jesus's feeling when they wore crosses because it reminded Jesus of his death.
