An outcry had gone against the two cities of Sodom & Gomorrah as early as the thirteenth chapter in the book of Genesis concerning a grievous sin.
Genesis 13:12-13 NKJV
12 Abram dwelt in the land of Canaan, and Lot dwelt in the cities of the plain and pitched his tent even as far as Sodom. 13 But the men of Sodom were exceedingly wicked and sinful against the LORD.
Again the same outcry & grievious sin is mentioned in the eighteenth chapter
20 And the LORD said, “Because the outcry against Sodom and Gomorrah is great, and because their sin is very grave, 21 I will go down now and see whether they have done altogether according to the outcry against it that has come to Me; and if not, I will know.”
When the angels finally visit Sodom & Gomorrah they mention again the same outcry & grievous sin to Lot
13 For we will destroy this place, because the outcry against them has grown great before the face of the LORD, and the LORD has sent us to destroy it.”
The men of these two cities try to have sexual relations with the two angels which culminates in the destruction of the cities.
Could this grievious sin have been referring to homosexuality?
