"Among the many accusations which in hours of ill-luck have been thrown out upon Lincoln, it is remarkable that he has never been called self-seeking, or selfish. When we were troubled and sat in darkness, and looked doubtfully towards the presidential chair, it was never that we doubted the goodwill of our pilot—only the clearness of his eyesight. But Almighty God has granted to him that clearness of vision which he gives to the true-hearted, and enabled him to set his honest foot in that promised land of freedom which is to be the patrimony of all men, black and white—and from henceforth nations shall rise up to call him blessed."
