It is the presence of this unction on the preacher that creates the stir and friction in many a congregation. The same truths have been told in the strictness of the letter, but no ruffle has been seen, no pain or pulsation felt. All is quiet as a graveyard. Another preacher comes, and this mysterious influence is on him; the letter of the Word has been fired by the Spirit, the throes of a mighty movement are felt, it is the unction that pervades and stirs the conscience and breaks the heart. Unctionless preaching makes everything hard, dry, acrid, dead.
This unction is not a memory or an era of the past only; it is a present, realized, conscious fact. It belongs to the experience of the man as well as to his preaching. It is that which transforms him into the image of his divine Master, as well as that by which he declares the truths of Christ with power. It is so much the power in the ministry as to make all else seem feeble and vain without it, and by its presence to atone for the absence of all other and feebler forces.
This unction is not an inalienable gift. It is a conditional gift, and its presence is perpetuated and increased by the same process by which it was at first secured; by unceasing prayer to God, by impassioned desires after God, by estimating it, by seeking it with tireless ardor, by deeming all else loss and failure without it.
How and whence comes this unction? Direct from God in answer to prayer. Praying hearts only are the hearts filled with this holy oil; praying lips only are anointed with this divine unction.
Prayer, much prayer, is the price of preaching unction; prayer, much prayer, is the one, sole condition of keeping this unction. Without unceasing prayer the unction never comes to the preacher. Without perseverance in prayer, the unction, like the manna overkept, breeds worms.
