This is the best book I have ever read on how Christians should relate to money.
As you'd expect, there's plenty on giving, and it avoids the dangers of legalism and ignoring tithing - I love his picture of tithing as being how God trains people to give. But there's also plenty on when saving is good (and when it isn't), the dangers of legacies, training children to have a good attitude to money, dealing with debt, and so on. But practice is always rooted in good theology.
If I were going to come up with one criticism, it's that his section entitled "Is it right for Christians to have material possessions and enjoy them?" gives the right answer but underplays it. There is a real danger in some cases of people feeling guilty for enjoying anything when they feel they should give more. Admittedly, the danger for far more people is that they assume that they should be comfortable and only give God what is left over.
Oh, and it doesn't mention Fairtrade stuff either.
Great book. Highly recommended. If you know of better money-related books, I'd love to know!
