So I started into Spurgeon’s Lectures and got about, well, more or less, about a page in before I was “arrested” by his helpful thinking. Here’s a taster
…
We are, in a certain sense, our own tools, and therefore must keep ourselves in order. If I want to preach the gospel, I can only use my own voice; therefore I must train my vocal powers. I can only think with my own brains, and feel with my own heart, and therefore I must educate my intellectual and emotional faculties. I can only weep and agonise for souls in my own renewed nature, therefore must I watchfully maintain the tenderness which was in Christ Jesus. It will be in vain for me to stock my library, or organise societies, or project schemes, if I neglect the culture of myself; for books, and agencies, and systems, are only remotely the instruments of my holy calling; my own spirit, soul, and body, are my nearest machinery for sacred service; my spiritual faculties, and my inner life, are my battle axe and weapons of war.
Your library, your laptop, your office, your desk, your starbucks tab are all secondary. The real tools of the trade for a preacher are their heart and their head, their own inner life and spiritual walk.
