The Fall of Sodom

When you think of Sodom and Gomorrah, what's the first thing that comes to mind? It's OK to say it. God destroyed them because of rampant sexual sin, right? I always thought that, until I read this:

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. Ezekiel 16:49

God's wrath wasn't because of their actions (which were sin), but because of the condition of their hearts. Their selfishness and lack of compassion ultimately led to their demise.

This has really been messing me up lately. What is the condition of my heart? Am I any better than the people of Sodom? Are you?
