There is alot of good info and I have found most to be correct teaching but it references books in the bible that according to my beliefs and faith shouldn't be included from the apocrapha(don't even know if I spelled it correctly).
Z.I.B.B.C. - NT. 4 vol's is and excellent resource to have for further study into the background of the NT. There are plenty of end notes made available for one to search out for themselves and expand on their understanding. Appreciate the fact that they have also given much time to mention the non-canonical sources that can also be used to glean from and is not only limited to just biblical books themselves and a bunch of obscure commentaries.
As a layman myself with only two years of college to my credit it is an invaluable resource for a more serious study
