"What can we spare?" vs. "What will it take?"

Some friends of mine have been impacted by the book Radical by David Platte, so I got it from the library to read during these 2 weeks of vacation.  One reviewer said this book kept him constantly saying either "Amen!" or "Ouch!"--in a good way.  David Platt challenges us to consider how much we (American Christians) have bought into the ideas behind the "American Dream," and challenges us to live radically, as the Bible truly calls us to.

If I owned this book, no doubt I would be underlining and writing notes all over the place.  Maybe I'll buy it later.  But for now, let me share a quote:

"How many people have not believed because they have not heard?  What will it take for those people to hear?  Have they not heard because there is no one to tell them?  What can we do, in obedience to God, to change a world in which there are millions and millions of people who cannot call on the name of the Lord? Most of us would say we know the answer to that question.  Many of us would say we are even doing things to change the situation.  But the truth is, there will continue to be millions and millions of people who do not hear as long as we continue to use spare time and spare money to reach them.  Those are two radically different questions.  "What can we spare?" and "What will it take?" (qtd in Radical, by David Platt, p. 129)
