Other religions don't really believe that you have to accept their faith in order to be saved. If you're a Christian, you must accept Jesus, and that's the only way to get to the kingdom of heaven when you die. Most Christians believe that if you don't accept Jesus Christ, that when you die, you will not be able to enter the kingdom of heaven. 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.
