There is no prayer that is unanswered. There may be requests that are unfulfilled, but there is a difference between the request and the prayer. A request has conditions; prayer is for openness. If you truly pray to be open, you will be open. If you pray for insight and understanding, you will be open to achieve that. If you pray for peace, you will be open to recognize the true peace that is present. It is understandable that human beings pray for specific outcomes whether personal or collective, regardless of the kind of outcome. Those prayers are often with conditions, and when it appears those conditions are not being met, it is easy to surmise that you didn’t deserve the prayer being fulfilled or that there was no one to hear that prayer. In other words, “there is no God, because if there were a God, my prayer would be answered.” Such prayers miss the point.
