Hi David,
All the names mentioned by
@Reformed are great. I would add Benjamin Keach (1640-1704), one of the leading Particular Baptists of the 17th Century. His
Marrow of True Justification (SGCB) is an excellent outline of that doctrine and
The Travels of True Godliness (also SGCB) is an allegory somewhat along the lines of Bunyan's
Holy War. True Godliness visits the houses of a variety of characters: Riches, Poverty, Youth, Old-Age, Legalist, Formalist, Apostate, and finally Thoughtful. Each of these is attended by a number of servants, relatives or friends. It's a very entertaining read with some excellent lessons to be learned.
Also by Keach is his massive
Preaching from the Types and Metaphors of the Bible. It's described as Keach's masterpiece, but I bought it some time ago, and I'm ashamed to say that I have scarcely glanced at it. I think the size of the thing puts me off!
Anything by Thomas Watson is good, especially
A Body of Divinity (Banner of Truth). Also, I recently read
Precious Remedies against Satan's Devices (also banner of Truth). a very encouraging book.
If you're worried about the Coronavirus, reading
God's Terrible Voice in the City by Thomas Vincent (Soli Deo Gloria Publications) will scare you to death! It's an account of the Great Plague of London of 1665 and of the Great Fire of the following year. Vincent was an eye witness of both events, and warns sinners of greater catastrophies awaiting the impenitent.
