So what gems have you found on books.logos.com?
גַּם־חֹשֶׁךְ֮ לֹֽא־יַחְשִׁ֪יךְ מִ֫מֶּ֥ךָ וְ֭לַיְלָה כַּיּ֣וֹם יָאִ֑יר כַּ֝חֲשֵׁיכָ֗ה כָּאוֹרָֽה
Nothing so far that made me grow new hair on my bald spot, I'm afraid. Alternately, what I did not find, but fully expected to: Pentecost's "Things To Come"..... for which I fully expect to be stoned or at least publicly castigated for even mentioning.
"I read dead people..."
It's a great discussion starter. My problem is that I've got a backlog so large on my reading list (with new things preempting items continually when they come to my attention) that I'll never get caught up. So if there's nothing to bring specific resources to my mind, nothing is likely to be added to my list, let alone be classified as a gem. So this resource collection has not yet been designed to be very useful to me.
Additionally, I should add that my reading and research are not often enhanced by public domain materials because the methods and understandings from so long ago is is either incorporated in secondary sources or irrelevant.
Brother Mark:what I did not find, but fully expected to: Pentecost's "Things To Come"
This book was published after 1929 so it's not in the public domain. Therefore, you won't be seeing it on books.logos.com.
Also, shame on you for reading a dispensationalist. (I couldn't hold back!)
