The Institutes of the Christian Religion: John Calvin
The Institutes are, I think, the greatest, deepest, and most extensive treatment of the grace of God I have ever read. Tim Keller
Pilgrim's Progress: John Bunyan
Next to the Bible, the book that I value most is John Bunyan's Pilgrim's Progress. I believe I have read it through at least a hundred times! It is a volume of which I never seem to tire; and the secret of its freshness is that it is so largely compiled from the Scriptures. It is really Biblical teaching put into the form of a simple yet very striking allegory. C.H Spurgeon
The Bruised Reed: Richard Sibbes
The Bruised Reed, quietened, soothed, comforted, encouraged and healed me. Martyn Lloyd-Jones
Confessions: Augustine of Hippo
Augustine offers his Confessions as a grand narrativisation of the journey toward, true wisdom: knowledge of God and knowledge of oneself. John Calvin
Precious Remedies Against Satan's Devices: Thomas Brooks
My soul can feed upon such blessed food as that and be satisfied with it. C.H. Spurgeon
Christian In Complete Armour: William Gurnall
If I might read only one book beside the Bible, I would choose The Christian in Complete Armour. John Newton
Valley of Vision: Ed. Arthur Bennett
When used slowly, for meditation and prayer, these pages have often been used by God’s Spirit to kindle my dry heart. Mark Dever
Holiness: J.C. Ryle
A book I think every Christian should read. It is so readable, so accessible, a very simple style of presentation, but absolutely forceful, and discerning. Every time I read it the Lord uses it to press upon me the importance and the possibility of holiness. Kevin DeYoung
