The gospel is the message preached by Christ and His church. Its focus is God's purpose and plan to reproduce Himself. Christ, John the Baptist and the apostles generally call it the "gospel of the Kingdom of God," but biblical writers use over a dozen other titles to describe it. Ultimately, it is the complete message of the entire Old and New Testaments, containing the message of what God the Father and His Son have done, are doing and will do to accomplish their purpose. It contains detailed information on the King, subjects, laws and territory of the Kingdom of God and how mankind can become part of it.
