I have known a lot more "Christians" who sell out for a lot less. Just like Lot's wife. Mr. McDonough has certainly done a righteous deed in this matter - now he should look at other matters of righteousness.
Luke 12:34
For where your treasure is, there your heart will be also.
You can't help but admire McDonough for sticking to his beliefs, even if he's poised to lose as much as $1 million in paydays
