Ok, let's forget the Bible for the time being (not that anyone follows it).
What should people be following?
It seems in the modern world, the only religion seems to be that of money and personal achievements. Despite what words come out, most people seem to be chasing these goals, with money being their true God. Our schools, our society, our leaders and everyone in between is pushing this on us. It has been this way for years.
The religions, including Christianity, teach people to be modest, humble, spiritual, etc. but the people live the exact opposite way. It seems that people just wear religion as an exoskeleton. It really doesn't affect their day to day life in any way. If it did, the conduct of people would be different - would it not?
The way things are and have been, religion is a giant game perpetrated on the masses to keep them feeling good about themselves.
Just for facts sake:
With the amount of wealth Christianity, Hinduism, Judaism, Islam have, they could eradicate poverty and malnutrition. You are talking about hundreds of billions of dollars of wealth here, if not more.
Well, no, the religions don't teach that at all. They command rape, slaughter, genocide, (sex) slavery, etc. At least that is the case for the Abrahamic religions. I think Jainism and Hinduism are pretty decent ones; they're not too big on the whole violence thing. Buddhism would be as well, if it weren't for the fact that it enacts two classes, with the non-Buddhists being serfs at the best of times.
And aye, you're right that most people do not follow their religion, thankfully. As we've seen in the Middle East, with Muslims that do follow the teachings of Yahweh...They're not too pleasant to live near.
As for what people should follow instead, there are two answers.
1. If it's a concept they want, then morality. Do good, help the innocent, punish the evil. As an example: don't kill a woman because she was raped and did not scream, even though the Bible tells you to. Offer her support, and get rid of the rapist instead.
2. If it's a figure they want, Fred Rogers seems like a great guy. Everybody oughta be like him. Failing that, Christopher Hitchens. Both, if people want a Pantheon.
On the subject of wealth, the Catholic Church, the ol' end game of the Roman Empire, has a fortune of a couple trillion pounds. They could reshape Liberia into a pretty nice place with that kind of money. Alas, raping children and donning fanciful robes is much higher on the to-do list.
