Before Sodom was destroyed an old man visited the town. He walked around trying to encourage the people to change their ways but not a soul would listen.

So, he decided to make a sign. In big bold letters he wrote the word “Repent.” He carried the sign day and night but again the people refused to listen.
So, he decided to take a more drastic approach. He ran up and down the streets yelling, “Repent! Repent! What you’re doing is wrong! If you don’t stop, you will die!” Again no one listened. Yet, he didn’t stop. He kept on running and yelling, “Repent!”
Finally, a local man stopped him on the street and asked, “Can’t you see no one is listening.”
The old man replied, ” Yes, I know.”
Confused the local man asked, “So, why on earth do you keep yelling?”
“At first I tried to change the people, now I run up and down the streets yelling so they don’t change me.”
