Ezekiel 16:48-50, 53-54
As surely as I live, declares the Sovereign LORD, your sister Sodom and her daughters never did what you and your daughters have done. 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. Therefore I did away with them as you have seen...
However, I will restore the fortunes of Sodom and her daughters and of Samaria and her daughters, and your fortunes along with them, so that you may bear your disgrace and be ashamed of all you have done in giving them comfort.
As I see it, the "sin of Sodom" discussion is like Jesus' ****ogy of the speck vs. beam - if I point in condemnation at "them", I have to deal with my own issues of being "arrogant, overfed and unconcerned".
