they dragged Jason and some of the brothers before the city authorities, shouting, “These men who have turned the world upside down have come here also, (Acts 17:6 ESV)

The Kingdom of God has often been referred to as the “Upside-Down Kingdom”, because many of the values of God's Kingdom are the exact opposite of values that popular society espouses, for example: humility over pride, sacrifice over opportunism, etc. (More on that here)

To turn this world upside down, then, is to truly make things right-side up.
