That's a big difference between Christianity and many other religions that people practice. People that are Christian also believe that Jesus will return one day, that that will be judgment day. We didn't talk about all the books of the Bible, but the last book is Revelations, which tells of basically a day where the world ends and that Jesus will be sent to save all of the people that believe in him. So there's a lot of faith in Christianity, that you must have faith in Jesus in order to be saved. Another big aspect of being a Christian, other than accepting Jesus for eternal life, is that you need to live that life while you're on earth like Jesus did. You need to love not only God, not only yourself, not only other Christians, but also your enemies as well. The turn your other cheek idea, kind of the idea of pacifism and peace and love and being humble and helping the poor, that's another huge idea in Christianity.
