As a comment on E Haynes's review (as of another favourable review too), see my review of Davies's book here.
I quote extracts from it, slightly modified, summarizing my reason for giving Davies only a 2-star rating:
"I am making rather a campaign of what I have to say here, and it is this: it is empty talk to discuss religion without concentrating on the historical records of the New Testament and the historical person of Jesus Christ, as observable `secular' realities, not only as objects or constructs of faith. I simply will not accept, that we do not know what religion is, or what we may mean by God, that we can either have no ideas about these matters, or else that we have to talk about the priest-king of Frazer's Golden Bough, or the Polynesian `cargo cults' of the 19th and 20th centuries, or African animist religions, or the Buddha, or whatever or whoever. ... What I am insisting on is that the New Testament and Jesus Christ must be put into the centre of every discussion of religion. To discuss God, say, or the nature of the soul, by quoting some smart maxim from Descartes or Wittgenstein, and to leave out what Jesus and Paul and the whole New Testament have to say about God, and the soul, and morality, and eternal life, is to me simply farcical."
