What is the significance of the statue of Jesus Enrique encounters?

A statue of Jesus Christ greets Enrique and others as their train enters Veracruz. It is a symbol of the unexpected charity that the migrants will receive. When Enrique sees a woman and a boy running alongside the tracks, he fears they will throw rocks. Such pessimism makes sense, considering his negative experiences so far in Mexico. So when the family throws not rocks but gifts, they give him more than food; they give him hope.
