The Privilege, Promise, Power & Peril of Doctrinal Preaching

by Thomas J. Nettles

Therefore it is manifest, from my text and doctrine, that no degree of speculative knowledge of religion is any certain sign of true piety. Whatever clear notions a man may have of the attributes of God, the doctrine of the Trinity, the nature of the two covenants, the economy of the persons of the Trinity, and the part which each person has in the affair of man’s redemption; if he can discourse never so excellently of the offices of Christ, and the way of salvation by him, and the admirable methods of divine wisdom, and the harmony of the various attributes of God in that way; if he can talk never so clearly and exactly of the method of the justification of a sinner, and of the nature of conversion, and the operations of the Spirit of God, in applying the redemption of Christ; giving good distinctions, happily solving difficulties, and answering objections, in a manner tending greatly to enlighten the ignorant, to the edification of the church of God, and the conviction of gainsayers, and the great increase of light in the world; if he has more knowledge of this sort than hundreds of true saints of an ordinary education, and most divines; yet all is no certain evidence of any degree of saving grace in the heart. (Works, 2:43)
