Mark 13:19-23

because those days will be full of trouble. There will be more trouble than there has ever been since the beginning, when God made the world, until now, and nothing as bad will ever happen again. God has decided to make that terrible time short. Otherwise, no one would go on living. But God will make that time short to help the people he has chosen. 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.
