Acts 26 is a chapter in the Bible that tells a story about a man named Paul. Paul believed in Jesus and went around telling people about him. One day, Paul was arrested and brought in front of a king named Agrippa to be questioned.
When asked to defend himself, Paul explained his story. He talked about how he used to be someone who didn't believe in God or Jesus, but then he had an experience where he saw a bright light and heard a voice from heaven. This experience made him believe in Jesus and he started telling other people about him.
Paul also explained that some people didn't like what he was saying and tried to stop him, even putting him in jail. But he continued to believe in Jesus and spread his message.
When Paul finished speaking, King Agrippa was impressed and said he almost believed in Jesus too. Even though Paul was in trouble with the law, he took the opportunity to share his beliefs with others and try to convince them to believe in Jesus as well.
