While researching a verse in a debate with someone on Christianity, I came across a verse that surprised me.
It still amazes me, how you can read the Bible over and over again, and still come across stuff that is fresh and new to me.
Ezekiel 16:49 (NASB) "Behold, this was the guilt of your sister Sodom: she and her daughters had arrogance, abundant food and careless ease, but she did not help the poor and needy."

When it comes to Sodom and Gomorrah, it seems we always focus on the sexual aspect of it. But it looks like the true sin lies in this verse here. In an abundance and a lack of sharing.
