Jesus asks whether they went out to see a reed shaken by the wind, or someone dressed like a courtier--the last things to which anyone would compare John. There was nothing supple about him, as Herod found, and Herodias (Mark 6:17-20); he was not shaken by the wind; there was no trimming of his sails. The austerity of his life and the austerity of his spirit go together, and he preached in a tone and a language that scorched. He preached righteousness, social righteousness, and he did it in a great way. He brought back the minds of his people, like Amos and others, to God's conceptions and away from their own. Crowds of people went out to hear him (Mark 1:5). And he made a deep impression on many whose lives needed amendment (Matt. 21:26, 32; Luke 20:6).[27] We have the substance of what he said in the third chapter of St. Luke; how he told the tax-collectors to be honest and not make things worse than they need be; the soldiers to do violence to no man and accuse no man falsely, and to be content with their wages; and to ordinary people he preached humanity: "He that hath two coats, let him impart to him that hath none; and he that hath meat, let him do likewise." It may be remarked of John, and it is true also of Jesus, that neither attacked the absent nor inveighed against economic conditions, as some modern preachers do with, let us say, capitalists and the morality of other nations. Neither says a word against the Roman Empire. Slavery is not condemned explicitly even by Jesus, though he gave the dynamic that abolished it. The practical guidance that John gave, he gave in response to men's inquiries. Like an Old Testament prophet (cf. Amos 3:2), John tore to tatters any plea that could be offered that his listeners were God's chosen people, the children of Abraham. Does God want children of Abraham?--John pointed to the stones on the ground, and said, if God wanted, he could make children of Abraham out of them; a word and he could have as many children of Abraham as he wished. It was something else that God sought.
