It is very interesting to see how many of Barna's insights into our culture have been realised with a direct impact on church and community. I think it has 2 points in particular that are very relevant to how we live life. 1) we guard our time jealously so that it isn't wasted. We have so many things taking our time and using it up that we won't do things if we think it is being needlessly wasted. We'll waste money sooner than time. 2) There has to be a reason for us to do things, and the reason is based on one of our priorities. The rest of the book explains further insights into the culture and many are pretty accurate
