The ancient world looked for a messiah.  False messiahs came and went.  Jesus was crucified, and yet His followers proclaimed the rejected Jesus to be the promised Messiah.  “And every day, in the temple and from house to house, they did not cease teaching and preaching that the Messiah is Jesus” (Acts 5:42).  The good news/gospel is that the risen Messiah is Lord of heaven and earth.  He has come to take back the creation from the powers of darkness.  His divine conspiracy is a new earth wherein dwells righteousness.  We are in on the plot.
