When rich and poor stand opposed to each other, Jesus never takes His place with the wealthier, but always stands with the poorer. He is born in a stable; and while foxes have holes and birds have nests, the Son of Man has nowhere to lay his head…. Both the Christ, and also just as much His disciples after Him as the prophets before Him, invariably took sides against those who were powerful and living in luxury, and for the suffering and oppressed.
