You may not understand the concept of a religious perspective of a supreme being. The idea is that this being cannot be completely understood by humans because humans were not given the ability to understand Him. In fact, the only one who can truly understand the nature of the Supreme Being is He Himself. Therefore, one cannot question the nature of the Being or the intent behind the decision. In a religious perspective the Supreme Being has given us a limited logical framework along with the world. Asking what causes this being to make decisions would be the equivalent of asking what causes the being to continue to exist.
Then why even bother asking the question?
And how can you say that we cannot know a Suprene Being's intent and then go on to say this:
My answer would be along the lines of reward for those who listen to his words. The reason for this world was not for us to serve; rather, the purpose of this world is for us to have a reward. Everyone religious would believe that there is a reward for following the rules. If our sole purpose was to worship than why would there need to be any reward? Furthermore if the sole purpose of the world were for the Creator to be worshiped, why would any blasphemy be tolerated at all? The sinners should be destroyed the instant they sin. In my framework, the purpose of our existence on this world is to earn a reward that is set-aside for us on another world. The reason for creating the world is because it is the "nature" (so to speak) of the creator to want to give to others.
The whole purpose of this world was to create others to give to.
Bolding mine.
You claim to know the nature and intent of the Creator after just saying that Its nature and intent cannot be understood by us puny humans.
Refer to my signature for my thoughts on this.
"You are metaphysicians. You can prove anything by metaphysics; and having done so, every metaphysician can prove every other metaphysician wrong--to his own satisfaction. You are anarchists in the realm of thought. And you are mad cosmos-makers. Each of you dwells in a cosmos of his own making, created out of his own fancies and desires. You do not know the real world in which you live, and your thinking has no place in the real world except in so far as it is phenomena of mental aberration." -
