Hi friends, A friend of mine sent me a message: "I am doing a class at Biola on Jeremiah, and I have a paper on the New Covenant. My prof specifically wants me to examine this subject as addressed by Jeremiah and also the NT. I swim in progressive dispensationist waters here, and that is how I am currently leaning on the matter, but I want to get the Reformed take on the matter. Do you have some good books I can read on the subject?" Y'all are far more knowledgeable than I; what book(s) would you recommend to this brother? Thank you.
