Note: I'm not one of Jehovah's Witnesses, and I'm not promoting one religion over another; however, if you really want more guidance on this subject then email the World Headquarters of Jehovah's Witnesses and they'll send somebody out to personally answer your questions and deliver free books on any subject that interests you. All this at no cost or obligation on your part.

I've done business with many of their people ( I find them both honest and trustworthy) and I've donated to their work so they can offer free info on such matters.

Best wishes in your search for truth...
