The truth of this matter is well documented. Truth states that such individuals have been
"given over to a reprobate mind." Their indecency and vulgarity has become a permanent part of their entire make-up (body, soul, and spirit). They are doing what is natural for the one who has been turned over to a reprobate mind.
In the story of Sodom & Gomorrah; when the homosexuals were literally struck blind by the angels of God, they still demanded the fulfillment of their sexually deviant desires. Their minds have been spiritually eaten up by sin, as cancer eats up an organ of the body physically. Their minds have been given over to the darkness; and they are bound by their own lust for one another, "doing that which is unnatural," and an abomination unto God.
Hey, and don't foget those heterosexuals who do that nasty stuff. I think the angels nailed a few of them to the old brimstone.
