Some Hindus say they celebrate Christmas in India but You can't truly celebrate Christmas unless you're a true Christian because Christmas is the birth of Jesus yes but the birth of the second Adam the last Adam (1 Corinthians 15) the savior of the world in which the Hindus don't believe in, I'm a missionary and I have friends in India and they are persecuted. The true sense of Christmas is not a Christmas tree and giving gifts , it's the birth of the savior of the world and apart from Jesus you don't get into heaven and if you don't get into heaven there's only one other option which is hell. Read the Bible.
