Let me see if I have this right.
God is the all-powerful, all-knowing, all-good creator and ruler of the universe. He knows everything, including what will happen in the future. He created us, gave us the capacity of reasoning and understanding, and we think we have the free-will to exercise those capacities – but since he has already determined and knows the future, this must be an illusion. He punishes us if we make the wrong choice that he knew we would make and likewise rewards us for good deeds. He requires that we pray to him at frequent intervals to praise him over and over again, and perform various kinds of rituals, like fasting, and wrapping ourselves in prayer garments. He requires us not to eat certain foods, and he prescribes how we should slaughter and prepare others. If none of this makes sense that is ok, God tells us it does not matter is we don’t understand, the main thing is to believe in spite of not understanding. Understand?
