Yes, the preacher's work is at the best a supremely hard one. The sense of this hardness must get into his soul, or else all hope of success will be vain. Should there ever come to him a moment in which it shall appear an easy thing to preach, or when his knowledge of the congregation awaiting him shall seem to indicate that "anything will do," then let him, in that moment, consider himself in peril of missing the true end of his calling. _Anything will not do_. The very best will hardly do! Think of the hardness of the heart! Think of the arguments of the tempter! Think how fair and sweet sin often seems! Think of all the sacrifice and self-denial and self-surrender we are asking from men! Here is need for the utmost diligence; for the development of every latent power of persuasion; for the employment of every ounce of energy, of every resource of skill; for the expenditure of every volt of passion the soul can contain. We can only hope to capture the citadel when the utmost possibilities of attack are brought to bear upon it. Even then the garrison may hold out against us! And the ultimate possibilities of attack are the ultimate possibilities of appeal. We speak of appeal as a quality that must pervade the whole of the sermon. We have heard counsels on preaching in which advice was given about "_the_ appeal" or "the _final_ appeal," whereby were meant certain perorative paragraphs; the remainder of the discourse being divided into "introduction," "exegesis," "argument," "illustration," "application." We remember some of these perorative paragraphs, and sometimes we have been tempted to ask whether the same note is struck in the preaching of to-day as was sounded forth in their stirring words. In spite of the homilists the sermon was generally better than their advice concerning its making and its form. The paragraph in question, though, perhaps, neither the preacher nor his adviser suspected the truth, was only powerful because it formed the climax of all that had gone before. It was the final assault following upon processes of sapping and mining, bombardment and fusillade. The appeal must commence _with the first word of the sermon_. The very introduction must be persuasive. The _motif_ of the whole composition must be the wooing note. Obviously this note will need to be struck in many keys. The appeal will have many expressions; and in their variety and form the skill of the preacher will have such room for exercise and such need for it as no other duty of his life displays.
