Spurgeon: Preaching is hard work

“I have heard of a brother who trusts in the Lord, and does not study; but I have also heard that his people do not trust in him; in fact, I am informed that they wish him to go elsewhere with his inspired discourses, for they say that, when he did study, his talk was poor enough, but now that he gives them that which comes first to his lips, it is altogether unbearable. If any man will preach as he should preach, his work will take more out of him than any other labour under heaven. If you and I attend to our work and calling, even among a few people, it will certainly produce a friction of soul and a wear of heart which will tell upon the strongest. . . .”
