Barnaby Rudge by Charles Dickens

In the exhaustless catalogue of Heaven's mercies to mankind, the power we have of finding some germs of comfort in the hardest trials must ever occupy the foremost place; not only because it supports and upholds us when we most require to be sustained, but because in this source of consolation there is something, we have reason to believe, of the divine spirit; something of that goodness which detects amidst our own evil doings, a redeeming quality; something which, even in our fallen nature, we possess in common with the angels; which had its being in the old time when they trod the earth, and lingers on it yet, in pity.

How often, on their journey, did the widow remember with a grateful heart, that out of his deprivation Barnaby's cheerfulness and affection sprung! How often did she call to mind that but for that, he might have been sullen, morose, unkind, far removed from her -- vicious, perhaps, and cruel! How often had she cause for comfort, in his strength, and hope, and in his simple nature! Those feeble powers of mind which rendered him so soon forgetful of the past, save in brief gleams and flashes, -- even they were a comfort now. The world to him was full of happiness; in every tree, and plant, and flower, in every bird, and beast, and tiny insect whom a breath of summer wind laid low upon the ground, he had delight. His delight was hers; and where many a wise son would have made her sorrowful, this poor light-hearted idiot filled her breast with thankfulness and love.
