Samuel Miller (The Importance of Gospel Truth):
Doctrinal preaching is of exceeding great importance in promoting the interests of true religion. There is, I am aware, in the minds of very many professing Christians, a strong prejudice against dwelling much on doctrine in the pulpit, as being, almost necessarily, dry and unprofitable; nay, as being adapted to repress rather than excite pious affection. This is a delusion as irrational as it is deplorable. It cannot be denied, indeed, that doctrinal preaching may be, and has been conducted, sometimes in such a dry, speculative, and spiritless manner; and, at other times, so much in the spirit of angry controversy, as to prevent all sanctifying influence. But this abuse is no argument against its use. If men are regenerated and sanctified by the truth; — if "the priest's lips ought ever to keep knowledge;" — if it be the duty of every preacher to "feed the people with knowledge and with understanding;" — and if none are so likely to be brought either to a saving acquaintance with the truth, or more thoroughly and affectionately under the power of truth, as those who have it constantly exhibited to them in a clear, discriminating and powerful manner; — then, surely, that minister of the gospel whose sermons do not contain a large portion of doctrinal and practical truth, clearly defined, adequately defended, rightly divided, and faithfully applied, — applied not merely to the understanding, but also to the conscience and the heart — is chargeable with essential deficiency in his official work. He may, possibly, be instrumental in producing temporary feeling, and even strong excitement; but not, without a miracle, in extensively promoting intelligent and solid piety. Men become Christians, as you have heard, by receiving, loving and obeying the great and precious doctrines of Christianity. Can it require evidence, then, to prove that gospel hearers are never so likely to become enlightened and genuine Christians, as when these doctrines are distinctly, strongly and solemnly presented to their view; and that believers are never so likely to be built up in faith and holiness, as when that which is the daily food of the spiritual life, is most plentifully set before them? All reasoning, and all experience go to establish the position, that that minister who does not habitually instruct, as well as exhort his hearers, cannot be, long together, to the same people, or to any people, a weighty, powerful, and edifying preacher.
