When the story starts, Daniel is an emotionally-barren young man driven entirely by his hatred of the Romans. His memories of his happy home life are vague, and his devotion is to Rosh, the bandit leader who occasionally strikes Roman targets. Daniel believes that Rosh will someday lead a rebellion and force the Romans out of Israel. His ideas are challenged first by Joel and Thacia, who show him unwarranted kindness, and then by meeting Jesus, who is preaching in the village. Daniel sees leadership in Jesus and in his heart wishes for him to lead the rebellion. However, the lesson he learns is far deeper; that of kindness and altruism.
He tried to cling again to the words of David that had always strengthened him. He trains my hands for war--
But Jesus said that the Victory was God's promise. He called men to make ready their hearts and minds instead.
Was it possible that only love could bend the bow of bronze?

From Jesus, Daniel learns that his personal quest is not as important as his effect on others. His actions have consequences, affecting everyone around him, including the people he loves. Two close friends die directly because of his drive to hurt the Romans. Daniel, through his epiphany of Jesus and his teachings, is finally able to abandon the hatred that has rules his life and embrace love and compassion.
