There may be some truth (atheists) do not need to believe in a god to be good, but then if they do not believe in a god, who do they believe gives the Universal Law of following good and shunning evil? Obviously, mankind. But then that is a dangerous thing, for if a man does not believe in a god capable of giving perfect laws, he is in the position of declaring all laws come from man, and as man is imperfect, he can declare that as fallible men make imperfect laws, he can pick and choose what he wishes to follow, that which, in his own mind seems good. He does not believe in divine retribution, therefore he can also declare his own morality contrary to what the divine may decree simply because he believes there is no divine decree. He may follow his every whim and passion, declaring it to be good when it may be very evil, for he like all men is imperfect, so how can he tell what is verily good? The atheist is in danger of mistaking vice for good and consequently follow another slave master and tyrant, his own physical and mental weakness. Evil would be wittingly or unwittingly perpetrated, therefore, to recognise the existence of a perfect divine being that gives perfect Universal Laws is much better than not to believe in a god, for if there is a perfect god, they will not allow their laws to be broken with impunity as in the case with many corrupt judges on earth, but will punish accordingly in due time. Therefore, to be pious and reverent is the surest path to true freedom as a perfect god will give perfect laws to prevent all manner of slavery, tyranny and moral wantonness, even if we do not understand why they are good laws at times.
We in the West regard the universe as a creation of God; like an invention or a product. After he created the universe, God set himself to oversee it and manage it. We see God as our boss. He created the universe, he is present in it, he manages every part of it, but he is still separate from it. It's like he installed video cameras all over the universe, so he can see everything that happens, and he can cause this or that to happen, but he is not a part of what happens. The Eastern view is very different. To the Hindu, for example, God didn't create the universe, but God became the universe. Then he forgot that he became the universe. Why would God do this? Basically, for entertainment. You create a universe, and that in itself is very exciting. But then what? Should you sit back and watch this universe of yours having all the fun? No, you should have all the fun yourself. To accomplish this, God transformed into the whole universe. God is the Universe, and everything in it. But the universe doesn't know that because that would ruin the suspense. The universe is God's great drama, and God is the stage, the actors, and the audience all at once. The title of this epic drama is "The Great Unknown Outcome." Throw in potent elements like passion, love, hate, good, evil, free will; and who knows what will happen? No one knows, and that is what keeps the universe interesting. But everyone will have a good time. And there is never really any danger, because everyone is really God, and God is really just playing around.
