In today's Reading 1 at Mass from Genesis 18, Abraham intercedes for Sodom. He asks the Lord if he will sweep away the innocent with the guilty. The Lord agrees that if he finds fifty innocent people in Sodom, he will spare the whole place for their sake. Abraham keeps asking what if there are forty-five, forty, thirty,... innocent people. Finally, the Lord agrees that he will not destroy Sodom if there are at least ten innocent people.
What I learn here is that holiness (being innocent) means a great deal to the Lord. Be holy and you can sway him from his plan.
