Nannie came in and sat down by the fire and began to read. She was very much interested in the book she was reading; but, somehow, to-day she did not like it as well as usual. She turned over the leaves, and read a little here and there; but it didn't please her. She got up from her chair, went to the window, and began drumming on the window-pane. "Be still, Nannie," said her father, who was sitting in the room, reading. She sat down again, and sat looking into the fire. "I don't care," she thought; "Jack had no business to do it. I think he was very unkind, and I'll do the same to him another time. Yes, I will," she said to herself more determinedly, because there was something within which said, _"If thy brother sin against thee, forgive him."_ Nannie wouldn't listen, but kept cherishing the angry thoughts. "He may be thankful it wasn't Belle instead of me, for she would have told father of him in a minute. Jack is always teasing me. He spoiled all my card-houses yesterday. Forgiving him then didn't do him any good." The little voice within whispered, _"Lord, how oft shall my brother sin against me, and I forgive him? till seven times? Jesus saith, Until seventy times seven."_ Nannie heard it again, but still wouldn't listen, and went on,--"And the other day he tore my prettiest paper doll, just for fun. I'd like to know how he'd like to have me tear his things 'just for fun.' "And the other day he hurt poor pussy's ears." The little voice whispered,--"And the other day, when you were sick, he stayed away from the nutting party, and showed you pictures, and read to you;" and as fast as Nannie told of an unkind act, the little voice whispered of a kind one. But Nannie could not listen to-day to the friendly voice which had so often helped her out of her troubles. After supper Jack said again, "Come, Nannie, let us be friends, won't you?" Nannie had let the angry thoughts have dominion so long, that although she felt almost inclined to make it up with Jack, pride conquered, and she turned away without a word. Poor Jack! he really loved his little sister very much, and had felt very sorry about the quarrel. It had cost a good deal of effort to go so far towards making it up, even though he knew he was to blame. But now, instead of being sorry, he was only angry, and turned away, saying, "Well, I can stand it as long as you can." That night, as Nannie lay awake, the little voice that Nannie had neglected so long kept whispering, _"Let not the sun go down upon thy wrath."_ She tried to think of something else, but it kept whispering, whispering. "I don't see," she said, "why I need trouble myself so about it. Belle wouldn't mind it a bit."
