Largely to the union of the intellectual and emotional elements mentioned--the definiteness of the message, the logical unity of the thought, the singleness and sincerity of the aim, the intensity of the conviction, the thorough knowledge of Scripture, the profound acquaintance, through personal experience, of the religious movings of the human heart--must be attributed, in connection with the state of religious thought and feeling of the time and the respect aroused by the character of the preacher, the power which he exercised on his contemporaries. Of his manner of preaching we have from his pupil, Hopkins, the following authentic testimony. "His appearance in the desk was with a good grace, and his delivery easy, natural and very solemn. He had not a strong, loud voice, but appeared with such gravity and solemnity, and spake with such distinctness, clearness and precision, his words were so full of ideas, set in such a plain and striking light, that few speakers have been so able to demand the attention of an audience as he. His words often discovered a great degree of inward fervor, without much noise or external emotion, and fell with great weight on the minds of his hearers. He made but little motion of his head or hands in the desk, but spake as to discover the motion of his own heart, which tended in the most natural and effectual manner to move and affect others. "As he wrote his sermons out at large for many years, and always wrote a considerable part of most of his public discourses, so he carried his notes into the desk with him, and read the most that he wrote; yet he was not so confined to his notes, when he wrote at large, but that, if some thoughts were suggested, while he was speaking, which did not occur when writing, and appeared to him pertinent and striking, he would deliver them; and that with as great propriety, and oftener with greater pathos, and attended with a more sensible good effect on his hearers, than all he had wrote."[13] * * * * *
