3. _Consecrate a specific part of each day to severe systematic work in the privacy of the study._ The habit of general observation and reading, before suggested, can be no adequate substitute for this. The time thus appointed for hard study should be sacredly devoted, and no ordinary occurrence be allowed to interrupt. The advantages of this are obvious. (1.) A habit once fixed is an ever-increasing power. The mind acts with greater rapidity and force when the habit of study at fixed, regularly recurring periods is formed. Instead of spending hours in vain attempts to fix attention and concentrate thought on the subject in hand, the mind enters at once with full energy into work. The more fixed and long continued the habit, the more easy, rapid, and powerful the mental processes. This is one secret of the immense amount of brain-work performed by some men: by fixed habits they instantly concentrate mental force, and work at white heat. (2.) If these hours are once fixed, and are fully understood by the people, they will ordinarily be free from interruption. The congregation will conform to the pastor's plan and will respect his fidelity in preparing for their instruction on the Lord's Day. What part of the day should be selected for the study cannot be determined by any rule; it must depend partly on the minister's habits, and partly on the necessities of his position. Ordinarily, the morning is best. The liability to interruption is less, and it leaves the afternoons and evenings free for visitation, meetings, and social life. Let me add, nothing but a high ideal of the ministry and a fixed purpose to realize it will enable a pastor to persist in such a course of study. He must believe in it as a solemn duty he owes his God, his people and himself, or he will fail. Indolence is often fostered by a false dependence on genius or on the spur of the occasion to give effectiveness and brilliancy to public utterances. Unthoughtful hearers, also, will often praise the off-hand, unstudied sermons and discourage elaborate preparation. Besides this, there are obstacles to study in the pastor's work. He has cares connected with the sick, the afflicted, the erring; executive work in the organization and discipline of the church; and duties he owes society in the varied relations of life. These are often pressing, and the danger is that they crowd into the hours for study. Many a man circumscribes his own intellectual growth and pulpit power, making himself permanently a narrower and weaker man, by allowing these outside cares to destroy his processes of mental discipline and growth. Here nothing will overcome but a profound conviction that study--persistent, regular, life-long study--is the solemn, first duty of every man who ventures to stand up in the pulpit as an instructor of the people. Let other duties have their place, but the first, the most imperative duty of him who teaches others is to teach himself. SECOND, THE SUBJECTS.
