The secret or mystery of the gospel.
1. How does Paul know this secret? We were all orphans, widows and foreigners. Paul is now Jesus ' prisoner. Every moment of our lives is under the control of Jesus. Paul received the secret by revelation (2-5).
2. The mystery is the Gentiles are heirs together with Israel (6). Equal status of Jew and Gentiles. Jesus sent his followers out - the nations did not have to come to Israel. From creation salvation has been through Christ.
3. Paul would do anything to spread this secret. He had been commissioned to spread the message of unsearchable riches.
