This is a book review of Packer's book, "In My Place Condemned He Stood." This book was really a love/hate relationship. I also knew that this would probably be the case heading into me reading it though as well. It is really 4 essays about the atonement of Christ. I found 3 of 4 to be very good and the one I figured I would find lacking is exactly the one that was lacking.

If you would like to read some additional material on why Packer's and Owen's understanding of the atonement are misleading, take a look at these posts:
A whole slew of quotes from Luther on the Atonement can be found at Calvin and Calvinism here.
Tony Byrne has done some great research as well and this post you should find helpful in this argument: Double Jeopardy? and also Penal Substitution
Lastly, take a look at Steve's blog and especially at this small post: Pecuniary vs Judicial Debt
