One of the things I have got wise to recently is the fact that if you are after a classic Christian book, the chances are that there will be a pdf version knocking around on the internet somewhere. This means that you can read them on your phone if you have a smartphone. So let me tell you what I currently have emailed to my phone, to read out and about. All of these are available if you google them and add ‘pdf’ to your search. By the way, I am happy to take others’ recommendations.
Spurgeon’s , ‘Lectures to my students’ three volumes, giving lots of advice on preaching. David Brainerd’s journal, edited by Jonathan Edwards. ‘The Reformed Pastor’ , by Richard Baxter. A book called Discipleship , by J Heinrich Arnold, full of challenging ideas. Individual Work for Individuals , by Trumbull . Method in Soul-Winning, by Henry C. Mabie . The Man God Uses by Oswald Smith (particularly excited about reading this one). Tortured for Christ, by Richard Wurmbrand. And ‘The Wisdom of the Sadhu’, based on the teachings of Sundar Singh. Not forgetting: ‘Questions People Ask about Religion’ by W.E. Sangster.
I know that often there is the temptation to have the very latest book on the subject. But the Holy Spirit anoints us and shows us what we need, and just what to read at the right time. He can save us a lot of unnecessary trawling if we listen to His promptings. And the needs of the human heart have not changed. Just google any of the above titles, and you should find them online. There is no excuse!
The other obvious thing to say in this connection is that there are some extremely good online libraries for Christian material, foremost of them being Project Gutenberg , and also Christian Classics Ethereal Library .
