IVP has a nice feature: each day you can go to http://www.ivpress.com/hardsay/ and read a free entry from their book Hard Sayings of the Bible.
I don’t agree with how they handle everything—not least their egalitarianism which ends up “explaining away” instead of “explaining” the author’s intended meaning. “Test everything; hold fast what is good” (1 Thess. 5:21).
(Walter Kaiser writes on OT passages; F.F. Bruce on Jesus’ sayings; and Manfred Brauch on the hard sayings of Paul.)
