You have a lot of faith in mans ability my friend, which is admirable. Unfortunately for me, I think 6000 years of mans history has thus far failed to show much promise. The last 100years have been especially noteworthy. Do you believe world peace will be achieved before world ruination?
If a master has two apprentices, one has correct instructions and the other was mistakenly given wrong instructions, and the first follows his instructions without due care, yet the second earnestly follows his instructions to a T, which do you think shows a more promising and employable attitude? if god is as just as scripture describes him to be, do you not think that ones demographics would be taken into consideration? Jesus teachings were that the greatest commandment was that you love god with your whole heart, your whole soul, and your whole mind, and that you must love your neighbour as yourself. If a man has everything else wrong, but keeps these commands, is he not fulfilling what has been asked of him? The question should be,Would a man if given the chance to do so correctly, serve god whole heartedly. That would be a fair and just measure of all mankind.
I do not know that my instructions are perfect and pure, although I am very confident in my judgement, I thus study hard and do my best to follow the guidance I glean from it. I would hope that Allah, Vishnu or Thor would note my efforts should I be incorrect.
