I’ve recently finished reading James Dolezal’s All That Is In God. Thoroughly enjoyed it. Messed with my head a bit. Worthwhile, stimulating, and right (imho)!
It’s caused a bit of a stir in the States, mainly because he’s critical of such saints as Don Carson, John Frame, and Bruce Ware. I’d pretty much agree with the reviews given by Andrew Wilson and Kevin DeYoung.
It’s worth getting hold of if you’ve never thought through issues of divine simplicity, immutability and eternity. He also has some great things to say about how language works in describing God. Its only 130 pages long and it will do all sorts of important, wonderful, and useful crazy-making to your brain.
