This was altogether more than Amy could bear; she made a bitter reply, and a quarrel began between the sisters, which made their walk to school very uncomfortable. It was so different from yesterday, Amy felt ready to cry, but she was ashamed that Kitty should see. Poor Amy entered the school-room with a sore heart. A bad temper is not likely to get sweet of itself, so Amy went on more and more discontented with herself, and her lessons, and everything else, until the class was called to read their morning lesson. The text from the Bible which stood at the head of the lesson happened to be, "For if you, from your heart, forgive not your brother his trespasses, how can your heavenly Father forgive you your trespasses?" Amy had to read these words, and they struck to her heart; she thought of what sinful and angry feelings she had been cherishing, and how much she had to ask God to forgive her, and how little she felt inclined to forgive in her sister and others; and afterwards, as she wrote her copy, hot tears fell on the page, and she confessed her fault in her heart to God, and begged him to forgive her. Then she felt happier at once. After school, one of her school-fellows was kept in to finish a sum; she was crying, and did not seem able to do it, so Amy went quietly to her, and showed her the way, and then danced off to the play-ground. On their way home she had a harder struggle to make, and that was to tell Kitty she was sorry for her hasty words; but she conquered, and Kitty having confessed that she too had been in the wrong, the sisters felt happy again together. This was true repentance; it was a sorrow for and confession of sin, and then forsaking the sin; it was a change of mind. That evening Amy felt very serious when she thought over the day's doings; she was weaker than she had thought--it was harder to do right than she had believed; but she resolved to try harder again to-morrow. So she went to bed hopeful, although rather sad. We shall see how her resolutions were carried out. CHAPTER V. TRY AGAIN.
