In the selection of subjects, I suggest: (1.) The subject should be, as far as possible, adapted to the existing state of the people. This requires an intimate, vital relation between the life of the pastor and the actual living of the people, for the isolated recluse will waste much of his pulpit work on subjects which do not touch the real experiences and life of his hearers. (2.) Every subject should be selected with earnest prayer for Divine guidance. God alone knows what are the real needs of those who will hear; and a theme thus chosen is delivered with authority as a message from Him, for a sermon is a growth with the preacher's soul, possessing vitality and power as the product of the Holy Spirit; and when thus obtained from God by the inworking of the Spirit, it becomes to the hearers a Divine message such as should be borne by "ambassadors for Christ." EXPOSITION. This method of preaching has of late years gone into disuse, partly because success in it is really difficult to attain, and partly because, the Bible having ceased to be the chief reading of the churches, the popular interest in exposition has decreased; but when rightly followed it has advantages, both to minister and people, beyond those of any other form of preaching. ADVANTAGES TO THE PREACHER.--It promotes exegetical study and acquaintance with the original Scriptures, the neglect of which is fostered by an exclusively topical method. The process is an ever-enriching one, constantly widening the range of biblical and theological knowledge. It ensures against sameness. Instead of growing stale, the preacher becomes more rich and varied in his range of thought and illustration with every added year. It gives, moreover, familiarity with the forms of Scripture thought and expression, and thus adds simplicity and force in addressing the Christian heart. Above all, it brings the preacher's soul into constant, living communion with the spirit of the Bible, and the study becomes in this way a fountain of religious life ever flowing into his heart, and out of it into the hearts of the people.
