Christians, are Hindus condemned to hell for believing in Brahma, Vishnu and Shiva?

Yea, there is no other name given among men whereby we must be saved, the Bible says. So unfortunately, yes it's either Jesus or hell fire. Any who were foreknown by God, though, will be saved.. even if he has to visit them himself. Which he has done on many occasions. Lots of Hindus and Muslims have been visited by Jesus, we get reports of that all the time.
