Its good. Basically it has only one point to make, but its an important point that many, many people in churches need to hear. And it makes that point well.
Its quite a short read - it feels more like an extended sermon than a book - and Rob Bell's writing style gets a bit irritating occasionally.
when he wants
one line of text
which can be just a bit
But anyway. The point is this: the western church of today (specifically in the USA, but mostly applicable to the UK too) has forgotten what it was like to be oppressed. And as a consequence we don't do the 'good news to the poor' bit of the gospel anymore. We preach at them, from a distance, but don't get alongside the poor, care for them and meet their needs. And we need to if we want to truly be followers of Christ - because that is what he did.
Of course, the book says that with a lot more bible quotes, stories and theology in there, but that's the main point.
Recommended, if you want a short but challenging read.
