I know this is an old thread, but in case anyone checks, Ravenhill's recommendation "Deeper Experiences of Famous Christians" will be available free this month at Classic Christian eBooks:https://www.classicchristianebooks.com/free-books/ They also have a bunch of Andrew Murray's books for free.
Thanks for highlighting this brother!

Saints,I just posted also a Top 50 Christian Book List recommendation list from SermonIndex: https://www.sermonindex.net/top50/This list is not conclusive and I might add to it from time to time. But overall these are books that either myself (Greg Gordon, Founder of SermonIndex) recommends or other godly men who I have spoken with recommend.
I am just now finding this old thread and it reminded me of another list of best Christian Books. This one is from Frank Viola and while I haven't read everything on his list, I recognize many gems in there. Have a look here:https://frankviola.org/top100/-Daniel
