Jesus just told his disciples that he would suffer many things, be rejected by his generation, and then leave them (25). They would desire to see him, but he would not be with them for a long time (22). He would, however, eventually return. The whole world will know when he returns. No one will say to another, “Jesus is over there. Come with me and see” (23), for when he comes, he will be like the lightning, which flashes and lights up the sky. When Jesus comes, he will be a brilliant light like he was on the Mount of Transfiguration (24).
Jesus says that when he comes again, the people will be as the people of Noah’s time when the flood came (26, Genesis 7:11-12, 23) and Lot’s time when Sodom and Gomorrah were destroyed (28, Genesis 19:23-25). They were not ready because they did not believe in God. They did not keep watch because they believed in themselves.
Jesus warns of the trap many fall in. He said, “I tell you, on that night two people will be in one bed; one will be taken and the other left. Two women will be grinding grain together; one will be taken and the other left.” (34,35)
Jesus wants his people to keep watch and be ready. Jesus said, “Therefore keep watch, because you do not know on what day your Lord will come,” (Matthew 24:42) and “So you also must be ready, because the Son of Man will come at an hour when you do not expect him”. (Matthew 24:44)
