It can make readers feel a sense of purity. When reading about innocent characters and their simple, untainted views of the world, it can wash away some of the cynicism that the real world might have brought.
Another example could be 'Charlotte's Web'. Fern's love for Wilbur, a little pig, is full of innocence. She is a child who sees the value in all living things and tries to protect Wilbur from being slaughtered. The whole story, with the simple and kind-hearted interactions among the animals, also reflects innocence.
Once upon a time, there was an old priest in a small town. He was a very incorruptible priest and his family liked him very much.
One day, the priest suddenly fell ill and his family was very worried. But they didn't know what to do because they had never heard of any doctor or doctor who could cure the priest's disease.
Then the priest's friends decided to help him. They went to the hospital in the town but there was no doctor there who could treat the priest.
They decided to go to the church in the town because the priest in the church was very good at treating all kinds of diseases. They soon arrived at the church, but the church was holding a celebration and the priest had already left.
They decided to look for the priest, but when they found him, they found that the priest had passed away. They were very disappointed, but they also knew that if the priest had not left the church, they might have been able to find a doctor or a cure for the priest's illness.
This story tells us that honesty and generosity are important qualities for priests and that people should learn from them.
