'In Proverbs we see God identifying with the poor symbolically. But in the incarnation and death of Jesus we see God identifying with the poor and marginal literally. Jesus was born in a feed trough. When his parents had him circumcised the offering they made - two pigeons - was that prescribed for the poorest class of people in society. He lived among the poor and the marginalized, who were drawn to him even as the respectable were repulsed by him. We see the kind of life he led when he said. "Foxes have holes, birds have nests, but the Son of Man has nowhere to lay his head" (Luke 9:58). At the end of his life he rode into Jerusalem on a borrowed donkey, spent his last evening in a borrowed room, and when he died he was laid in a borrowed tomb. They cast lots for his only possession, his robe, for there on the cross he was stripped of everything. He died naked and penniless. He had little the world valued and the little he had was taken. He was discarded - thown away. But only because of Him do we have any hope.'
