God destroyed Sodom and Gomorrah with fire and sulfur. This had been done because of their disgrace. Their unrighteous deeds could not inherit the Kingdom of God. Neither the immoral, idolaters, adulterers, swindlers or thieves. The sodomites chose to live this way consistently so God gave them over to these dishonorable passions.
For as he thinks in his heart, so is he…. (Proverbs 23:7)
There is no gene that determines our preferences. Our perceptions are shaped by our environment, thoughts and beliefs. Lust for the same is unnatural it goes against nature. I’ve seen far too many precious lives lost because of sodomy. Friends have become engulfed with the lust until their demise.
