“The systematic theologian is pre-eminently a preacher of the gospel; and the end of his work is obviously not merely the logical arrangement of the truths which come under his hand, but the moving of men, through their power to love God with all their heart and their neighbours as themselves; to choose their portion with the Saviour of their souls; to find and hold him precious; and to recognise and yield to the sweet influences of the Holy Spirit whom he has sent. With such truth as this he will not dare to deal in a cold and merely scientific spirit, but will justly and necessarily permit its preciousness and its practical destination to determine the spirit in which he handles it, and to awaken the reverential love with which alone he should investigate its reciprocal relations. For this he needs to be suffused at all times with a sense of the unspeakable worth of the revelation which lies before him as the source of his material, and with the personal bearings of its separate truths on his own heart and life; he needs to have had and to be having afull, rich, and deep religious experience of the great doctrines with which he deals; he needs to be living close to his God, to be resting always on the bosom of his Redeemer, to be filled at all times with the manifest influences of the Holy Spirit. The student of systematic theology needs a very sensitive religious nature, a most thoroughly consecrated heart, and an outpouring of the Holy Ghost upon him, such as willfill him with that spiritual discernment, without which all native intellect is in vain. He needs to be not merely a student, not merely a thinker not merely a systematizer not merely a teacher – he needs to be like the beloved disciple himself in the highest, truest, and holiest sense, a divine.”
