This document discusses how the story of Shadrach, Meshach, and Abednego in the fiery furnace relates to Advent and being a church in exile. It notes that the three men refused to worship the king's idol and were willing to give their lives rather than serve any god except their own. Similarly, the church should pray for its host culture but not bow to their idols. The story teaches that Christians should be aware of places where their faith is illegal and idols seeking their worship even in their own communities.
