Answer and Explanation:
Jesus is part of the story of God's love for humanity because he decided to give up his divine nature in order to live, teach and sacrifice for humanity. According to the story, humanity lived in sin that kept it away from God, however, God sent Jesus, his son to sacrifice himself, taking the punishment of all mankind on himself, being tortured and killed, so that sin would be extinguished and humanity could stay close to God. This is represented in the short film presented, where the driver allows his son to die in a cruel way, so that the population inside the train can live. In this way, we can learn how God's love for humans is infinite and has allowed God to sacrifice his own son, for humanity to live.
In this short film, the driver represents God, the child represents Jesus and the train represents all humans.
