After I posted my note a couple days ago, Al Mohler posted a two-part series on the controversy.
Here's part one.
Here's part two.
R. C. Sproul, Jr., added this interesting article called, Can a Person Be Evangelical and Not Believe in Hell?
Then Justin Taylor added this excerpt and description called, Rob Bell on Martin Luther and Salvation in Hell. (Bell claims Luther believed one could be saved from hell after death.)
Finally, we have a review of the book itself (still not released yet) via a pre-release PDF version granted for review purposes. One of the most talented Christian book reviewers around has done that review for us.
Here's Tim Challies' review of Bell's book, Love Wins.
