We have all been conditioned by religion to believe that the Bible is some sort of supreme authority. Of course, we all know that the Watchtower Society, after claiming that the Bible is useful as this sort of authority, blatantly fails to follow it.
What would you expect some supreme authority to have? Its premises should be beneficial to all involved. But, what do you see when you look at the Old Testament, which has most of the rules? Look at the rules. You are supposed to make sacrifices, which waste resources that otherwise could go to the betterment of mankind. The Levites--what value do they create? NONE! All they do is take the tenth portion of the fruitages of others while not creating any themselves. And, all the wars--for what? So that people that do not worship God can all die to let a group of parasitical value destroyers plunder their land and destroy all valuables in their possession. Supreme authority?
What about the New Testament? It mostly lacks the kind of wanton destruction found in the Old Testament. However, is there any actual and real harm in fornication? Before you automatically say that there is, would you buy a car without test-driving it? Would you buy a house without at least testing the major appliances like the furnace, and inspecting for major problems and whether it will fit your needs and wants? Fornication is nothing more than test-driving a spouse. If things do not work out, one can terminate the engagement before major damage is done. If one blindly marries to avoid fornication, and the mate is impotent or abusive, what then?
Beyond this issue, Paul advocated going out and proclaiming the message at hardship to the one doing the proclaiming. He himself was a missionary, and suffered much and sacrificed much (which is where the major religions, including the Catholic church, modeled the Crusades after). It is here that anyone that questions God Himself or does something against God (note: not the Filthful and Disgraceful Slavebugger or some organization) will be condemned to Hell. And what is this "God"? Some higher cause that man is supposed to waste resources sacrificing to, that's what. Note that, in proper context, Jesus never once mentioned that people were supposed to waste resources in spreading the Gospel--it would spread itself once more people caught onto the freedom from corrupt religion and government!
A supreme authority would also have to be free of mysticism. Is the Bible? All one has to do is look at Genesis. A talking snake? The Flood? I don't think so! The Flood doesn't explain why the kangaroo and the taipan snake are only found in Australia, and why one cannot find lions, tigers, and bears together anywhere on the planet (if the Flood were true, there would have been lions, tigers, and bears together near where the Ark landed).
What about the parting of the Red Sea? Mysticism. True, a strong wind would have been able to push the water back. But, humans are about the same weight as water. Any wind that would be strong enough to push the water back to that depth would have also pushed any human back that is trying to walk against it. You would simply have been blown right back toward Egypt! Yet the Bible treats that event as the truth.
Finally, the mysticism of going to heaven. Most Christian denominations teach that at least some good people are going to heaven. Most also teach about Hellfire. The truth is that, what would anyone be doing in heaven? How would someone start ruling once they get there? If Jesus is in heaven now, then why didn't he lambaste the Watchtower Society, which he supposedly approved, when they started to deviate? And Slime Schroeder should for sure have disrupted this forum from heaven. The churches are not much better--they do not answer the question about what people are going to do, nor why people are not helped by dead loved ones that go to heaven. That is all a myth designed to get people to obey the rulers of the Church.
Hellfire is another myth. So the witlesses do not believe in it--they only believe that most people are going to be destroyed soon for not joining (which has failed to come true multiple times--more mysticism). But those believing that one is going to suffer in Hell are just as wrong. Why? How does heat cause suffering? By making it incompatible with life. By injuring living flesh. A spirit does not have any flesh to injure, and hence would not feel any pain no matter how hot it gets. It would also not need air, and would be impossible to poison with poisonous gases. In practice, even if one did make it to hell, one could find it quite bearable since there is no flesh to injure or torture. And, there is no reasonable proof that people live on after they die (and it cannot be proven reasonably).
I don't think the Bible is any good as an authority. It is full of myths, logical fallacies, and rules that cause waste and value destruction. It is full of stock prayer answerings and blessings that have been referenced so God will not have to deliver additional ones, which makes them mysticism. It is full of malediction for petty infractions of rules that are designed to make people waste value on some higher cause. Aside what Jesus himself wrote, and that's with the caveat that it was not to be taken literally, the Bible is one of the worst pieces of advice to follow. And, the Watchtower Society's littera-trash is probably the one major piece that is even worse.
It is better to look at it independently. Those philosophers that were warned against ("empty deception") are probably better to follow. Socrates was the first of those. Most of the Bible was modeled after Plato (the need for a bunch of rules). Aristotle disagreed--he felt that rules were mostly spurious and detrimental. Only by independently researching all of the above can you decide whether or not to follow the Bible, or parts thereof.
