When we pray for real, and don't just say words to God, we need to use than our lips. Praying is very different from reciting the Pledge of Allegiance to the flag at school, even though we are sincere when saying the pledge. We have to use our minds and think about what the words mean, and we have to use our hearts and try to feel the meaning of the words. When we thank God, we should be happy. And when we tell Him we are sorry for and bad or stupid things we have done, we should feel sorry.
