God is able to save to the uttermost all them which call upon His name. No specifics re:Buddha, Brahma, Vishnu, Muhammad, Confucius, The Great Spirit of the Indigenous Americans, Sikhism, Christianity, Shintoism, Gnosticism, and so forth. By their fruit shall ye know them. The One True God is not and never has been a "one-trick-pony". He's never been fitted into any man made theological boxes or "definitions". She is GOD period, and can do whatever the heck She wants to do, anywhere, at any time, in any manner She sees fit. All the rest is man made. Dem's da facts jack!......imo.
