Perhaps we need to be a little more precise as to WHICH GOD we are actually referring. Would you say that the god of other religions is the same God of Israel we read of in the Bible ?
And do other religions accept Jesus as the Son of God ?
Do they believe in keeping the Commandments and the Sabbath ? Not even traditional christians come into this category hence the whole world is out of step with God.
We should all concentrate on the most basic beliefs before arguing about details, don't you think ?
As I said elsewhere God is not saving all the world now but only groups of people to be the first from every nation. Others will be called progressively. He started out with one - Abraham , now he is calling thousands and later millions.
Yes, I believe that the God that is worshipped in other religions is the same God as the one that Jews, Christians and Muslims worship.
Which most basic beliefs are you referring to? Do you mean philosophical ones, moral ones or the ones you have stated above such as Jesus being the Son of God?
