I loved this article. Here is a synopsis of it.
Jesus wants us to be without pretense when we come to him in prayer. Instead, we often try to be something we aren’t. We begin by concentrating on God, but almost immediately our minds wander off in a dozen different directions. The problems of the day push out our well-intentioned resolve to be spiritual. We give ourselves a spiritual kick in the pants and try again, but life crowds out prayer. We know that prayer isn’t supposed to be like this, so we give up in despair. We might as well get something done.
