Jesus
Part of Christian belief is that Jesus Christ did not just come as a human person so that he could teach a better way of life. Christians also believe that Jesus was the ultimate sacrifice for the sin of humankind, that Jesus is the "Saviour": the one who is here to save. Christians believe that, unlike ordinary people, Jesus was completely pure and free from sin, but that when he died on the cross, he took on himself all the sins of every person who would believe in him, like the lamb sacrificed in the temple.
