Have you ever noticed that most Christian Prayer is like an old telegraph message, or like using a ham radio? It goes: Let Us Pray...{Prayer}.....AMEN. That is sorta like an old telegraph message with the message going ..{Line}..STOP.....{Line}.....Stop or a Ham Radio operator calling ..{Message}...OVER....
Just an observation I was thinking about. Also, you could call the Cross a VERY simple antenna for directing the prayers to a supreme being.
