Here’s a great deal on a handful of Bible commentaries. I was recently introduced to the Christ-Centered Exposition Commentary series. Each chapter of each volume ends with discussion and reflection questions. These would be a great for use in a small group setting or to deepen your personal study of the Bible. The series is projected to be 48 volumes. Sale price on each of these ends March 21, 2017 but these are still good commentaries.
