Final answer:
According to Luke 21:9, wars and revolutions will occur before the end of the world, but the end itself will not come immediately.
Step-by-step explanation:
According to Luke, chapter 21, verse 9, Jesus states, 'When you hear of wars and revolutions, do not be frightened. These things must happen first, but the end will not come right away.' In this verse, Jesus is referring to the signs of the end times and indicating that even though wars and revolutions will occur, the actual end of the world will not happen immediately.
