As we are both not supreme beings there is no way of justifying or rationalising any religious faith based doctrine or whatever.I don't contradict myself. The Supreme Being already stated that all men have fallen and remain fallen. Their sins can only be redeemed by the blood of Jesus. People need to accept Jesus as their Saviour.
Nobody can follow their religious rules 24/7 to remain in a perpetual state of purity and perfection. And anything short of that is insufficient to be perfect so that they can gain entrance into paradise.
Often religious would say "god works in mysterious ways"
It is all faith based. You cant prove or rationalise it.
Perhaps there is no supreme being and it is just figment of our imagination.
