I don’t think these things actually change your DNA so to speak but I have read in the past that there are chemical changes in the brain in homosexuals (don’t know about the others) I think it’s pretty interesting since Romans chapter 1 tells us that he gives those who do not retain knowledge of him over to a reprobate mind.
I was just going with Leviticus and attempting to relate it to the matter, what with the soul being in the blood, then you have the consequence of various sins being described as their blood being upon them, blood cries out, on to other books with marriage being one flesh, the condemnation of men lying with men who receive the just recompense of their error within their own bodies which is meet, it goes on.
There are literal, physical consequences of some sins, within the body, is what that tells me. Being forbidden to eat pork in the Old Testament, lo and behold, pigs are remarkably similar to humans in ways very important to modern medical science. Trichinosis, too, but the genetic closeness in certain aspects, I can’t help but wonder if that played a part.
The sin of that mark has a physical component. Turns you into something unrecognizeable and alien to Him, has to, all the above can be forgiven with repentance but this cannot be forgiven. It’s final.
One cannot do to their bodies what homosexuals do, which is far more than most have a clue about...without it affecting the mind. We do become the choices we make...Homosexuals change in their appearances as well over time...there's a real putrid look that eventually shows in their skin. Some will resort to body building etc. to offset the body changes.
That's likely because there's a closer connection between the soul and body than we realize.
I would figure that the practiced behavior causes the chemical changes rather than the chemical changes causing the behavior.
Science and scientists are not known for getting the order of things right and often put the cart before the horse.
