Mark 13:21-27

At that time, someone might say to you, ‘Look, there is the Christ!’ Or another person might say, ‘There he is!’ But don’t believe them. False Christs and false prophets will come and perform great wonders and miracles. They will try to fool even the people God has chosen, if that is possible. So be careful. I have warned you about all this before it happens. “During the days after this trouble comes, ‘the sun will grow dark, and the moon will not give its light. The stars will fall from the sky. And the powers of the heavens will be shaken.’ “Then people will see the Son of Man coming in clouds with great power and glory. Then he will send his angels all around the earth to gather his chosen people from every part of the earth and from every part of heaven.
