This is a sermon delivered on Sunday December 11th, 1859, by C. H. Spurgeon, at the Music Hall, Royal Surrey Gardens, upon the last occasion of his preaching there, when he was only 25 years old. He bases his sermon on the text in Acts 20;26-27—"Wherefore I take you to record this day, that I am pure from the blood of all men. For I have not shunned to declare unto you all the counsel of God." A faithful preacher must, like Paul, give his people the entire gospel of Jesus Christ. Spurgeon shows how important this is. Otherwise, the spirits of Christians will become marred and maimed.
