Jesus warns his disciples about future events related to the destruction of the temple in Jerusalem. When asked about the signs of these things, Jesus tells them to watch out for deceivers and warns that nation will rise against nation and there will be disturbances in nature. He describes signs in the heavens and says this generation will not pass before all these things happen. Jesus says no one knows the day or hour, instructing his followers to keep watch and be prepared. The overarching message is for believers to listen to Jesus as their shepherd, follow him, and stay alert as they watchfully await his return.
