FREE BIBLE STUDY TOOLS:
"[These] website[s] came in handy even when I was a seminary student. I especially appreciated the interlinear Bible which worked great with the corresponding BST Greek and Hebrew fonts. While it is no substitute for Logos, this website provides a number of helpful study tools for free—including commentaries, concordances, dictionaries, encyclopedias, and lexicons." ~ Dr. Nathan Buzenitz
There are well over two dozen commentary sets available on these sites. They also contain helpful articles and sermon transcripts from both classic and contemporary preachers and theologians.
THE THEOLOGICAL RESEARCH CENTER
"The featured resource on the site is a growing library of video lectures taught by the TMS faculty. These lectures can be watched, free-of-charge, by anyone with an internet connection. The site currently contains eleven full courses, consisting of more than 200 individual lectures." ~ Dr. Nathan Buzenitz
