Believing is behaving

This from Barbara Kralis of the Jesus Through Mary Foundation:

Lex orandi est lex credendi, translated into English as "The law of prayers dictates the law of belief." In other words, the way you pray shows what you believe; what you exhibit externally reflects what you believe internally. As Archbishop Fulton Sheen once said, "If you don't behave as you believe, you will end by believing as you behave."
