Acts 7 is a part of a book called Acts in the Bible. It is about a man named Stephen who talked to some people about Jesus. But some people didn't like what Stephen had to say and they got mad at him. They took him to the leaders and accused him of saying bad things about their religion.
Stephen then tells a long story about their past and how they had disobeyed God many times. He talks about Abraham, Joseph, Moses, and King David. He reminds them that they rejected Jesus, just like their ancestors had rejected the prophets sent by God.
The people who were listening to him got more and more angry and they eventually threw stones at him until he died. But even though he was killed, Stephen never stopped believing in Jesus and trusting in God. His story in Acts 7 teaches us about the importance of standing up for our beliefs, even if it gets hard.
