A lot of meditation and observation. I now give the Christian Bible, the Muslim Quran, and other "holy" texts the same consideration that I do the Gods of Ancient Rome, Greece, and Egypt. Every god-figure down the line has been man's creation or interpretation of what they believe happened. they are methods of controlling groups of people. Does it work? Youbetcha! 100%. Nope. Even your bible tells of those that ignored Jehovah. Where should I start? Adam and Eve eating the fruit from the tree of knowledge. Too often we see the dumbing down of citizenry in totalitarian states. Especially if the country isn't fully totalitarian, the dumbing down starts early and can take generations. Look for leaders that believe it is their family destiny to rule. Like Hillary this election. Jeb, also. Notice that you didn't see a single Kennedy on the Presidential ticket, although they are represented in Congress, as are other political families.
The silent majority won't shut up about how only "godly" men should lead our country. So far, I've only seen "godly" men lead us to war. While he didn't thump the bible as much as some, G W Bush was considered godly enough to lead us to invade Iraq. We see how that godly decision, based on lies and deception, is still playing out.
Nope. If I want a god of war, I'll build an alter to Mars. As for the God of Abraham? He's got some crappy press agents down here. For every godly act made in his name, I see a dozen representing your Satan using his name. No thanks.
