Jesus said:
(NASB) Luke 17:28-29 “It was the same as happened in the days of Lot: they were eating, they were drinking, they were buying, they were selling, they were planting, they were building:
29 but on the day that Lot went out of Sodom it rained fire and brimstone from heaven and destroyed them all.”

  The people in Sodom were going about the business of daily living…eating and drinking.  They were busy making a living…buying selling, planting, building;”
  Then here comes the “but”…(NASB) Luke 17:29 “but on the day that Lot went out from Sodom it rained fire and brimstone from heaven and destroyed them all.”

  God’s mercy is extended toward all who turn to Him in belief and repentance…His mercy is available until His judgment is given out.  How can we know this from a Biblically historical perspective?  (Genesis 18:20-33)
(NASB) Genesis 18:20-21 “And the LORD said, ‘The outcry of Sodom and Gomorrah is indeed great, and their sin is exceedingly grave.
21 ‘I will go down now, and see if they have done entirely according to its outcry, which has come to Me; and if not, I will know.’”

  What sin was “exceedingly grave”?  Homosexuality.
(NASB) Genesis 19:1-5 “NOW THE two angels came to Sodom in the evening as Lot was sitting in the gate of Sodom.  When Lot saw them, he rose to meet them and bowed down with his face to the ground.
2 And he said, ‘Now behold, my lords, please turn aside into your servant’s house, and spend the night, and wash your feet; then you may rise early and go on your way.’  They said however, ‘No, but we shall spend the night in the square.’
3 Yet he urged them strongly, so they turned aside to him and entered his house; and he prepared a feast for them, and baked unleavened bread, and they ate.
4 Before they lay down, the men of the city, the men of Sodom, surrounded the house, both young and old, all the people from every quarter;
5 and they called to Lot and said to him, ‘Where are the men who came to you tonight?  Bring them out to us that we may have relations with them.’”

  What does God say in the New Testament concerning homosexuality?  (Romans 1:18-32)
(Amplified) Romans 1:26-28 “For this reason God gave them over and abandoned them to vile affections and degrading passions.  For their women exchanged their natural function for an unnatural and abnormal one.
27 And the men also turned from natural relations with women and were set ablaze (burning out, consumed) with lust for one another – men committing shameful acts with men and suffering in their own bodies and personalities the inevitable consequences and penalty of their wrong-doing and  going astray, which was[their] fitting retribution.
28 And so, since they did not see fit to acknowledge God or approve of Him or consider Him worth the knowing, God gave them over to a base and condemned mind to do things not proper or decent but loathsome.”

Question: Are these days different from “in the days of Lot”?
