The good Lord had had a chance for a long time before the abolition. I believe that there is a moral government; and that God reigns. I am no pessimist; I give thanks to the good Lord, and also to the good men through whom He has worked. Prominent among them was Garrison, and scarcely less so was Phillips. It was they and their associates who made Abraham Lincoln and the Republican party possible. What abolished slavery was the moral sentiment which had been created, not by the pulpit, but by the Garrisonian platform. The churches did not do much to abolish slavery; but they did much to keep the agitation down.
