1. Jesus rebuked the leaders of Israel for their hypocrisy and failure to follow God's commands, condemning their behavior so they would repent before God's judgment.
2. When asked about the end times, Jesus described signs of wars, persecution and impostors that would occur both before the destruction of Jerusalem and throughout history, telling believers to endure and spread the gospel.
3. Jesus spoke of specific signs for his second coming including false prophets, celestial phenomena, and his visible return in glory, which will come as suddenly as lightning across the sky. He emphasized the importance of watching and waiting for his return at any time.
