His spirit of holiness, or Divine nature, He was clearly shown to be the Son of God by the fact of His resurrection. Now, the man who will patiently, steadily work out such an analysis of God's Word as he studies it will penetrate the heart of it, and its richness will astonish him. The great thoughts of God will be laid open to his view as they never can be to the careless, superficial reader; and if, with such biblical work in the study, the pastor devotes a part of the Lord's Day either to expository preaching or to a lecture in his Bible school, this direct connection of the work of the study with that of the pulpit will add interest and force to both. 2. _In the study of the Christian doctrines it is, first of all, important to have a system._ This plan of work should be so arranged that in a course of years, taking one subject at a time, the pastor may make a thorough investigation of all the leading topics. As the basis take such a work as Hodge's _Outline of Theology,_ or any good compendium of theology, and, following the order of subjects, work in each until its main points have been mastered. For illustration, suppose the subject is the doctrine of inspiration. First work out carefully the questions in your chosen text-book, and read some of the best authors on the subject, as Lee, Woods, Gaussen, and Hodge. All the points involved will thus be brought distinctly before the mind. Then collect the leading passages of Scripture bearing on it and examine each critically and patiently and note down your own impressions. Follow this by writing a full and careful statement of your own view as the result of the investigation. Or suppose the subject to be that great central doctrine of the Gospel, the atonement. After working out the questions as presented in your text-book and reading the best authors accessible to you, so as to become master of the vital points, then examine the priesthood and sacrifices of the Old Testament, the predictions of the atonement in prophecy, and the passages bearing on this doctrine in the New Testament. Having thus before you the elements of a decision, write out fully your own view. Such a process of theological investigation, steadily pressed year after year, and connected as it would be with the reading of the great masters in theology, could not fail to make the pastor a clear, strong religious thinker and his pulpit a power in leading religious thought. Let me also urge the study of the history of doctrines in connection with such a course of theological investigation. Take such a work as Hagenbach's or Shedd's _History of Doctrines,_ in which the course of theological thinking on each of the great truths of the Bible is traced through the ages, and the varying phases of the doctrine through successive periods, and the forms in which it has been held by the world's profoundest thinkers are presented. Such a study is wonderfully stimulating to thought and affords a broader basis for the formation of
