It may seem like a bit of a stretch to use Sodom and Gomorrah as an example and warning to us in the church today, but that is exactly what Jude did. One of the most obvious reasons that we are to put into remembrance this biblical account of sin and judgment is that it is prophetic of the condition of the last days.
I cannot think of a time in my years of following the Lord when I have seen greater immorality among those who claim to be followers of Jesus Christ. I cannot personally think of a time when I have seen more open and blatant sin taking place on the part of those who profess to be Christians.
When we hear the names Sodom and Gomorrah, we immediately think of immorality. But there were other things at the root of these sins. Ezekiel 16:49 offers God's assessment: "Look, this was the iniquity of your sister Sodom: She and her daughter had pride, fullness of food, and abundance of idleness; neither did she strengthen the hand of the poor and needy." These people were proud, they had more food than they needed, and they had too much time on their hands. What an accurate description of our nation today.
The pride of those who lived in Sodom and Gomorrah was a nationalistic pride. They felt strong and indestructible. And many feel that way today in the U.S. The problem is that we have forgotten God. We have done our level best to push Him out of our schools, out of our courtrooms, and out of our culture, and we are now seeing the results of it with the moral breakdown in our society.
