The immortality of the soul was infinite misery, because it is that which eternizes their misery, but when this overplus is added, the incorruptibility of the body, and so the whole man made an inconsumable subject for that fire to feed upon perpetually, what heart can conceive it without horror!— The Works of the Rev. Hugh Binning
What went with the overplus was known only to certain of his country-folk, whose ill venture after greater fortune in America had proved to be but a fiercer struggle with still greater poverty than they had struggled with at home; and no doubt the angels also kept track of his modest benefactions, for such is reputed to be their way Many a wounded life was healed by these hidden ministrations on the part of Andreas; and, as rightly followed, great love there was for him in many a humble heart.— An Idyl Of The East Side 1891
