This Sunday at Redeemer we kick off a new series through the book of Ruth. If you are looking for some good supplemental reading I highly recommend A Sweet and Bitter Providence, by John Piper. I typically use a mix of critical and theological commentaries in my study. For Ruth my top three are:
The Book of Ruth (NICOT), Robert L. Hubbard Jr. Judges-Ruth (NAC), Daniel Block A Critical and Expository Commentary on the Book of Judges, Andrew Fausset
And a HUGE thanks to Brian Malcolm who always designs such excellent sermon graphics for us.
To see more of our sermon art follow the "sermon art" tag.
