Thematic Bible: Why people partake in inappropriate sexual behavior

I [am] Yahweh your God, who brought you up from the land of Egypt. Open wide your mouth and I will fill it. But my people did not listen to my voice, and Israel did not yield to me. So I let them go in the stubbornness of their heart; they walked in their counsels.

And just as they did not see fit {to recognize God}, God gave them over to a debased mind, to do the things [that are] not proper, being filled with all unrighteousness, wickedness, greediness, malice, full of envy, murder, strife, deceit, malevolence. [They are] gossipers, slanderers, haters of God, insolent, arrogant, boasters, contrivers of evil, disobedient to parents, senseless, faithless, unfeeling, unmerciful, who, [although they] know the requirements of God, that those who do such things are worthy of death, not only do they do the same [things], but also they approve of those who do [them].
