These are the opening paragraphs to a broadcast of Breakpoint, a Christian radio perspective on the news. It is a ministry of Prison Fellowship. The folks at Breakpoint asked that we not post their information on other websites. You can visit the Breakpoint Archives to hear the real audio broadcast of the program. Just look for the "Hearing God's Call--Os Guinness' 'The Call'" broadcast.
