The New Interpreter’s Bible is a first-class 12 Volume commentary for students and preachers. It has useful reflections for each section to assist with sermon-starters. Until now we have often recommended that units buy the 2 Volumes Matthew-Mark & Luke-John for preparing Gospel-based sermons.
Now the whole 12 volumes is available in a software format for Windows and Mac users.
