The second example Jesus uses to compare the conditions of the time when he returns is the time of Lot.
28 Likewise also as it was in the days of Lot; they did eat, they drank, they bought, they sold, they planted, they builded;
29 But the same day that Lot went out of Sodom it rained fire and brimstone from heaven, and destroyed them all.
30 Even thus shall it be in the day when the Son of man is revealed.
How were the days of Lot? We can find the description in Genesis Chapter 19.
Sexual Perversion/Homosexuality– we discover the wickedness of Sodom is so bad it has reached heaven. One specific example of the unrighteousness we see here is a very strong, intense spirit of homosexuality. Our current generation is facing this same issue.
Easily Offended– in Genesis 19:9 we read the following, “This one fellow came in to sojourn, and he will needs be a judge”. They were offended because Lot was trying to protect the angels and forbid them from committing the evil homosexual act. Many individuals in this generation always complain of people “judging them” when you tell them they are doing something wrong. Jesus stated in Matthew 24 that men would be “offended” in the last days.
Life was normal until the day Lot and his family left Sodom. God had an escape plan for his people but the sinners were destroyed. Notice they were not totally removed from the earth but they were able to escape the fire and brimstone which fell upon Sodom.
