I've found that anything from the pen of Charles Spurgeon is like my favorite armchair; it is homely, comforting, familiar, reliable, not overly cozy, but after a spell in it...always refreshed & rested. He has the ability to be poignant, humorous, sensible, reverent, simple, practical, devotional, profound, lucid, jovial, biblical, and faithful with an almost unrivaled balance in all these areas.
Lectures to My Students is a book I've visited numerous times, and pogo-sticked around in for the last several years; however, I recently did a fresh breeze through again of its entirety, and it was just fabulous. These lectures to pastoral students (a category I currently fall into) are vital insights for men pursuing and in the pastoral ministry. He highlights the common folly's and temptations and the need to resist them. He offers practical, no-nonsense advice on a preacher's lifestyle, presentation, mindset, and approach. He never takes himself or his listeners too seriously, but this never detracts from the grave seriousness of the topic of preaching the word of God. He is hilarious, but never in a flippant way. He is pithy in his insights. He is tweet-able, 200 years before social media was in existence.
The first collection of lectures focuses on a minister's personal life and holiness; it is vital to never undertake to be a minister unless you are both inwardly called of God and outwardly called of God by the church. He confronts despair and depression in the ministers life, in my favorite chapter (The Minister's Fainting Fits). The second collection deals with preparation and study. The third on deliver and illustration. All of it is good ol' fashioned sense. Very practical. Very helpful.
