*doesn't know a lot about religion*
but don't christians think that jews are wrong. because the god came to the jews first. then it came to the christians with a new, modified and advanced message. isn't that right. but when islam was sent to the humans, "god" said that islam is his final word.
so the book you're taking all these quotes from must be wrong in the first place. otherwise, you're defying your own god, right? so who's commiting the bigger sin, you or me?
