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. And there's also a conversion aspect. Christians believe that it is their job to save other souls. If the only way to enter the kingdom is to accept Jesus Christ, then you need to make sure you spend your time on earth saving as many people as you can. Now, of course, Christians also believe that Jesus is not just a prophet. He's not like Muhammad in Islam or gurus in Hinduism. He is actually the son of God.
