Ortberg's discussion of boundaries resonated within me. He states that Christians use boundaries to dictate who is in their group and who is not. Drinking is a boundary. If you drink, you are outside my group. If you don't drink, you are inside the group. The same applies for smoking, dancing, caffeine, you name it. Ortberg implies that this is how many Christians live their lives. He says that our lives should be marked by a transformation of the heart, not by boundaries. Wow.
Another chapter highlighted the need to be quiet, to take things slow. This, he says, is necessary to hear God speak to us. That really does make sense. Being one who likes to speed (and people in Nashville drive SLOW), I found this chapter to be refreshing.
A lot of the book deals specically with spiritual disciplines in bullet fashion (before reading the Bible, do this, this, and this). That's where it started to get uninteresting. Not that this is not important. Far be it from that. But he starts the book with such fervor on the life we are all looking for as Christians and then moves to a bullet list of what to do. For me, I just found that change too much. But still a good buy.
