The question he addresses in this program relates to the issue of secularism - according to the dictionary, "the belief that religion and religious bodies should have no part in political or civic affairs or in running public institutions, especially schools; the rejection of religion or its exclusion from a philosophical or moral system." Secularism is perhaps the dominant force in our culture, and many hold to it "religiously" ("relating to or manifesting faithful devotion to an acknowledged ultimate reality; scrupulously and conscientiously faithful; fervent, zealous" - Webster's).
Here's a short quote from the Breakpoint transcript:
At a recent conference on Christian worldview, a college student asked the question: “Is there a model for engaging secularism?” The panel of well-known experts was stumped, clearly unfamiliar with the fact that 200 years ago a small group of politicians, bankers, writers, and lawyers addressed and overcame the crisis of secularism and immorality in England.
He goes on to discuss the work of William Wilberforce and his friends in early-19th-century England, as analyzed in a new book, edited by Chuck Stetson, entitled Creating the Better Hour: Lessons from William Wilberforce. Colson's program discussed one of the strategies Wilberforce used in some depth (well, as much depth as possible in a 5-minute radio program!); Stetson's book includes 10 such strategies. I'm looking forward to reading it. In the meantime, check out Colson's program - even the first taste of this model will likely help you impact your world more effectively.
