The End of the World Is Coming!

In verse 3, Jesus tells his disciples that the end of the world is coming. He says there will be a massive tribulation and signs before it happens. Then he goes on to tell them what's going to happen immediately after: The moon will not give its light; stars will fall from heaven. "What you thought was stable, what you thought was going to stay here, what you think will remain, is vanishing, gone"
