Speak for eternity. Above all things, cultivate your own spirit. A word spoken by you when your conscience is clear and your heart full of God’s Spirit is worth ten thousand words spoken in unbelief and sin. Remember that God, and not man, must have the glory. If the veil of the world’s machinery were lifted off, how much we would find is done in answer to the prayers of God’s children. — ROBERT MURRAY MC CHEYNE .

Unction is that indefinable, indescribable something which an old, renowned Scotch preacher describes thus: “There is sometimes somewhat in preaching that cannot be ascribed either to matter or expression, and cannot be described what it is, or from whence it cometh, but with a sweet violence it pierceth into the heart and affections and comes immediately from the Lord; but if there be any way to obtain such a thing, it is by the heavenly disposition of the speaker.”

We call it unction. It is this unction which makes the word of God “quick and powerful, and sharper than any two-edged sword, piercing even to the dividing asunder of soul and spirit, and of the joints and marrow, and a discerner of the thoughts and intents of the heart.” It is this unction which gives the words of the preacher such point, sharpness, and power, and which creates such friction and stir in many a dead congregation. The same truths have been told in the strictness of the letter, smooth as human oil could make them: but no signs of life, not a pulse throb; all as peaceful as the grave and as dead. The same preacher in the meanwhile receives a baptism of this unction, the divine afflatus is on him, the letter of the Word has been embellished and fired by this mysterious power, and the throbbings of life begin — life which receives or life which resists. The unction pervades and convicts the conscience and breaks the heart.

This divine unction is the feature which separates and distinguishes true gospel preaching from all other methods of presenting the truth, and which creates a wide spiritual chasm between the preacher who has it and the one who has it not. It backs and impregnates revealed truth with all the energy of God. Unction is simply putting God in his own word and on his own preacher. By mighty and great prayerfulness and by continual prayerfulness, it is all potential and personal to the preacher; it inspires and clarifies his intellect, gives insight and grasp and projecting power; it gives to the preacher heart power, which is greater than head power; and tenderness, purity, force flow from the heart by it. Enlargement, freedom, fullness of thought, directness and simplicity of utterance are the fruits of this unction.

Often earnestness is mistaken for this unction. He who has the divine unction will be earnest in the very spiritual nature of things, but there may be a vast deal of earnestness without the least mixture of unction.

Earnestness and unction look alike from some points of view. Earnestness may be readily and without detection substituted or mistaken for unction.

It requires a spiritual eye and a spiritual taste to discriminate.

Earnestness may be sincere, serious, ardent, and persevering. It goes at a thing with good will, pursues it with perseverance, and urges it with ardor; puts force in it. But all these forces do not rise higher than the mere human. The man is in it — the whole man, with all that he has of will and heart, of brain and genius, of planning and working and talking. He has set himself to some purpose which has mastered him, and he pursues to master it. There may be none of God in it. There may be little of God in it, because there is so much of the man in it. He may present pleas in advocacy of his earnest purpose which please or touch and move or overwhelm with conviction of their importance; and in all this earnestness may move along earthly ways, being propelled by human forces only, its altar made by earthly hands and its fire kindled by earthly flames. It is said of a rather famous preacher of gifts, whose construction of Scripture was to his fancy or purpose, that he “grew very eloquent over his own exegesis.” So men grow exceeding earnest over their own plans or movements. Earnestness may be selfishness simulated.

What of unction? It is the indefinable in preaching which makes it preaching. It is that which distinguishes and separates preaching from all mere human addresses. It is the divine in preaching. It makes the preaching sharp to those who need sharpness. It distills as the dew to those who need to be refreshed. It is well described as: “a two-edged sword Of heavenly temper keen, And double were the wounds it made Where’er it glanced between. ‘Twas death to sin; ‘twas life To all who mourned for sin.

It kindled and it silenced strife, Made war and peace within.”

This unction comes to the preacher not in the study but in the closet. It is heaven’s distillation in answer to prayer. It is the sweetest exhalation of the Holy Spirit. It impregnates, suffuses, softens, percolates, cuts, and soothes. It carries the Word like dynamite, like salt, like sugar; makes the Word a soother, an arraigner, a revealer, a searcher; makes the hearer a culprit or a saint, makes him weep like a child and live like a giant; opens his heart and his purse as gently, yet as strongly as the spring opens the leaves. This unction is not the gift of genius. It is not found in the halls of learning. No eloquence can woo it. No industry can win it. No prelatical hands can confer it. It is the gift of God — the signet set to his own messengers. It is heaven’s knighthood given to the chosen true and brave ones who have sought this anointed honor through many an hour of tearful, wrestling prayer.
