just got this last week and am super excited to use it!! I have been digging around in it a little bit already... one thing to be aware that I didn't realize is that there are 16 volumes to the PNTC set --- this package only gives you 15. It is missing the 2nd letter to the Corinthians which was printed in 2014, I suppose this package just has not been updated whether by oversight or on purpose - not sure. Either way, this is a great set of resources and worth every dollar!!! :) THANK YOU LOGOS!! BLESSINGS!
