who will be saved in the end? christian or non-christian?

how can you know that God answers? if you are saying that no religion is perfect, then all religion are sham, which implies that all of us will not be saved in the end. if only God knows how we will be saved, and if only He cares for our salvation, why did He not give His laws that could last till the end, as what you have said, old laws are too much out of tune with the reality of these days. if your God is powerful, why didnt he predict that what He had set for His people could not last till the end?

I agree not all religion is perfect. Not because God or His ways handed down to us through religion is imperfect but because man who practices these religions is imperfect. Which in turn spreads his imperfection to his religion.

Perfect or not perfect, no religion can save anybody. Only our deeds, physical or non-physical, will save us. God did not send down any religion to us here. He sent His message of dos and don'ts. That was what all the earlier Prophets were emphasising. It was only the so-called last prophet that claimed to have brought a religion from God. We should stop deceiving ourselves. God is constant and all-knowing. He couldn't have forgotten to hand down a religion to the earlier peoples only to remember the need for it at a later period. All religions are not from God; they all are artificial creations by man. That is why they are all imperfect and unable to stand the test of time.
