ABSTRACT
Every art is founded on some science, and every science is connected with some other science; it follows then, that every art is connected with all the sciences, and every science with all the arts. Theology comprehends all other sciences as its tributaries, and with a generous reciprocity diffuses through them all a genial influence; it derives illustrations from all arts, and returns a singular and sometimes scarcely visible aid in the prosecution of all. In the first place, theological study conduces to the preacher's eloquence, because it conduces to his greatest vigor of mind and heart. The vigor of mind and heart, which is gained from doctrinal investigation, is the mainspring of effective preaching. There is a second mode in which theological study increases the eloquence of the preacher; it gives him a proper confidence in himself and his ministrations.
