We did not have to fill the air with words to be in communion with one another. We did not have to say a lot of words to understand where each other was. If close friends can experience being in communion beyond the boundary of words, how much more can we be in communion with God beyond the boundary of words. Praying is being in a right relationship with God. But as is true of all relationships, praying, sooner or later, involves the use of words.
Prayer is more than words, and certainly prayer is never merely words.
But sooner or later prayer involves the use of words. Even my introvert friend and I needed to talk some. We did not need a lot of words, but we did need to talk some in order to stay in touch with what the other was thinking or feeling. We needed words to share information, or to share our joys, to give vent to our frustrations or to be helpful to one another when either of us was dealing with some pain or problem. If I were ever to use popular movies as a way of trying to teach some of the concepts of the Christian faith, I would choose Fiddler On The Roof as a conversation piece to talk about prayer.
