I must linger a moment over Robert Flockhart, of Edinburgh, who, though a lesser light, was a constant one, and a fit example to the bulk of Christ's street witnesses. Every evening, in all weathers and amid many persecutions, did this brave man continue to speak in the street for forty-three years. Think of that, and never be discouraged. When he was tottering to the grave the old soldier was still at his post. "Compassion to the souls of men drove me," said he, "to the streets and lanes of my native city, to plead with sinners and persuade them to come to Jesus. The love of Christ constrained me." Neither the hostility of the police, nor the insults of Papists, Unitarians, and the like could move him; he rebuked error in the plainest terms, and preached salvation by grace with all his might. So lately has he passed away that Edinburgh remembers him still. There is room for such in all our cities and towns, and need for hundreds of his noble order in this huge nation of London—can I call it less?
