Both Rosh and Jesus are seen by the villagers as men opposing the Roman rule over Israel. However, they are extremely different in their beliefs and methods. Rosh is a bandit living in the hills; he has been active for a long time, and people are accustomed to his rhetoric about eventually leading an army to rout the Romans. However, his excursions are always for theft and intimidation, and despite his words he never actually takes steps to move on Rome. In fact, he avoids confrontations with Roman soldiers because, as Daniel realizes, the Romans are content to allow Rosh his banditry as another method of keeping the villagers scared and dependent.
Suddenly words were echoing in his mind. "For each one of you is precious in His sight." Not scripture, but the words of the carpenter. That was what had confused him. Rosh looked at a man and saw a thing to be used, like a tool or a weapon. Jesus looked and saw a child of God.

When Jesus comes to the village, Daniel expects that he will use his great charisma and apparent supernatural powers to lead a revolution. However, Daniel soon realizes that Jesus is working towards changing hearts and minds; he is not trying to foster a violent rebellion, but instead trying to spread love and peace through the region. Jesus believes that since all humans are God's children, then peace will come through mutual love and understanding, not through war. This shows how Rosh is simply a user of people to his own ends, while Jesus attempts to enlighten people how to better themselves and others.
The author places Rosh and Jesus as two "saviors". They are both leaders but they have different motivation. Rosh is motivated by revenge and Jesus is motivated by love
