This may not be the sermon that you expect. It is not a sermon about old age. The language of grey hairs is taken to represent decay and decline, and applied to spiritual things in individuals. His concern is with people who are sliding into patterns of spiritual slovenliness and sin but who have no sense of such a departure from the path of real and lively religion. Why are they ignorant of this? Spurgeon offers some suggestions. What are the marks of decay and backsliding for which we should look? Spurgeon identifies some features of spiritual decline. Are there are any remedies? As a good physician of the soul, Spurgeon is ready to make some recommendations. It is not an easy sermon, as the preacher blends explanation and application, speaking plainly to expose our sins, cutting close lest anything should escape the knife, but also making sure that there is some gospel balm at the close for the healing of our wounds. Perhaps, though, we do not mind so much when it is Spurgeon, and we can close the book, or pause the podcast? Let us remember that this is faithful preaching, and our own pastors—if they look us in the eye and deal so straightforwardly with us—are doing the same job to the same end.
