A.W. Tozer emphasizes the necessity of continuous learning for ministers, drawing on wisdom from figures like Joseph H. Smith and John Wesley, who advocated for reading widely to enhance one's understanding and effectiveness in ministry. He likens the pursuit of knowledge to sharpening an axe, suggesting that a well-prepared mind makes the work of ministry easier and more fruitful. Tozer encourages ministers to prioritize their intellectual growth, as it honors God and equips them for their calling.
