Christian leaders are commending "Book of Virtues" author Bill Bennett for pledging to give up gambling after reports that he's lost (m) millions of dollars in recent years. While insisting that he didn't break laws or go into debt, Bennett released a statement admitting that he's "done too much gambling" -- adding that "this is not an example I wish to set." On C-B-N's "700 Club," the Reverend Pat Robertson said gambling can be addictive and that Bennett may need professional help as well as friendly support. Focus on the Family's James Dobson and Beverly LaHaye of Concerned Women for America agreed and said they'll pray for Bennett. Ken Connor of the Family Research Council said that while "opinions differ as to whether gambling is a vice, few would regard it as a virtue."
