As Jesus leaves the temple, the disciples point out its buildings, and he says not one stone will be left on another. On the Mount of Olives, the disciples ask when this will happen and what will be the sign of his coming and of the end of the age. Jesus warns that no one should lead them astray: many will come in his name saying they are the Christ, there will be wars and rumors of wars, famines and earthquakes, but the end is not yet; these are the beginning of birth pains. They will be delivered up to tribulation and hated, many will grow cold in love, but the one who endures to the end will be saved, and the gospel of the kingdom will be preached throughout the world, and then the end will come.
Jesus speaks of the abomination of desolation spoken of by the prophet Daniel standing in the holy place, and tells those in Judea to flee to the mountains. Then there will be great tribulation, with the days cut short for the sake of the elect. He warns against false christs and says his coming will be visible like lightning that comes from the east and shines as far as the west.
After the tribulation, the sun will be darkened, the moon will not give its light and the stars will fall; then the sign of the Son of Man will appear, he will come on the clouds with power and glory, and send his angels to gather the elect. Jesus teaches the parable of the fig tree: when its branches become tender, summer is near; so when you see all these things, know that he is near.
About that day and hour no one knows, not the angels nor the Son, but the Father only. Jesus commands watchfulness, because they do not know on what day their Lord is coming, and tells of a faithful and wise servant who cares for others and is found so when his master returns, while the wicked servant who beats his fellow servants and gets drunk will be punished.
