What was the sin that brought about God’s fiery wrath upon these cities?  Many other pagan societies survived for centuries without experiencing such horrendous judgment.  According to the Bible, God destroyed the cities because of their great immorality and perversion.  God did not want the Jewish people to be influenced by this evil.

When the LORD rained upon Sodom and upon Gomorrah brimstone and fire,  the Bible clearly states that the fire and sulfur, or brimstone, rained down “from the LORD out of the heavens”  (Genesis 19:24, ) not upward from a volcano.  Researchers were astonished to find that there is no evidence of volcanic activity in the area. Sulphur is always mined around Geothermal sites. Where did this pure sulphur come from?  Bible has the answer in Genesis 19:24  The Bible clearly informs us that the source of this brimstone had supernaturally came from God.

God has the divine right to destroy evil as he sees fit. The ancient ruins of Sodom and Gomorrah was a warning to other civilizations that God does not tolerate immorality and perversion.. We read in 2 Peter 2:6 – “God turned the cities of Sodom and Gomorrah into ashes, condemned them with an overthrow, making them an example unto those that after should live ungodly.”
The Bible records what Abraham saw: “He looked down toward Sodom and Gomorrah, toward all the land of the plain, and he saw dense smoke rising from the land, like smoke from a furnace” (Genesis 19:28). Dense smoke suggests smoke from a petroleum-based fire. Smoke rising like smoke from a furnace indicates a forced draft, such as would be expected from subterranean deposits being forced out of the ground under pressure.
God was mercifully willing to spare the cities for the sake of a few righteous people, but the in-laws were destroyed because they thought Lot was joking about God’s wrath.

It is not biblical to say that homosexuality was the exclusive reason why God destroyed Sodom and Gomorrah.  Clearly, homosexuality was part of why God destroyed the two cities.  Ezekiel 16:49-50 declares, “Now this was the sin of your sister Sodom: She and her daughters were arrogant, overfed and unconcerned; they did not help the poor and needy. They were haughty and did detestable things before me…” The Hebrew word translated “detestable” refers to something that is morally disgusting and is the exact same word used in Leviticus 18:22 that refers to homosexuality as an “abomination.” Similarly, Jude 7 declares, “…Sodom and Gomorrah and the surrounding towns gave themselves up to sexual immorality and perversion.” So, again, while homosexuality was not the only sin in which the cities of Sodom and Gomorrah indulged, it does appear to be the primary reason for the destruction of the cities.

Those who attempt to explain away the Biblical condemnations of homosexuality claim that the sin of Sodom and Gomorrah was inhospitality. The men of Sodom and Gomorrah were certainly being inhospitable.  But to say God completely destroyed two cities and all their inhabitants for being inhospitable clearly misses the point. While Sodom and Gomorrah were guilty of many other horrendous sins, homosexuality was the reason God poured fiery sulfur on the cities, completely destroying them and all of their inhabitants. To this day, the area where Sodom and Gomorrah were located remains a desolate wasteland. Sodom and Gomorrah serve as a powerful example of how God feels about sin in general, and homosexuality specifically.

This is a pretty stern warning for people today who insist on parading their perversion before the world.
