I received this email from World Magazine today. Even though it is a promotion for a new book I think it has value. I read the linked chapter and found it enlightening. In light of the controversy about same-sex marriage I thought it would be good to post it here because it attempts to answer questions that are brought up in most discussions of same-sex marriage these days. Sometimes the discussion gets bogged down in trying not to hurt feelings, etc. so that the important issue that homosexuality and other sexual deviations--including adultery--are sins is obscured. How can we be light to the nations if we, too, are in darkness?
