The Book of Job (in the Bible's Old Testament) is a long poem. The Book of Job discusses why innocent people suffer. God cares about people who suffer troubles. And God will help them, although sometimes they must be patient.
Job was a good man. But Job lost all his possessions. Job's children died. Job became so ill that he wanted to die. But Job refused to insult God.
Job's friends supposed that Job was ill because of his evil deeds. But Job was innocent. Then, a wise man named Elihu explained the truth to Job and his friends. And God proved to them that God is great. God also showed them that he cares. Finally, God wanted Job to pray for his friends. In the end, God made Job successful again.
