Jeremiah 15:12

Shall iron break the northern iron and the steel?

The northern iron and steel

In order to achieve a purpose there must be sufficient force. The weaker cannot overcome the stronger. In a general clash the firmest will win. You cannot cut granite with a pen knife, nor drill a hole in a rock with an anger of silk. We shall apply this proverb--

I. To the people of God individually.

1. Many Christians are subjected to great temptations and persecutions; mocked, ridiculed, called by evil names. Persecuted one, will you deny the faith? If so, you are not made of the same stuff as the true disciple of Jesus Christ; for when the grace of God is in them, if the world be iron, they are northern iron and steel.

2. We are frequently called to serve God amid great difficulties. Will you say, there is no converting these dark and obdurate souls? Is the iron to break the northern iron and steel? Look at Mont Cenis Tunnel, made through one of the hardest rocks; with a sharp tool, edged with diamond, they have pierced the Alps. As St. Bernard says: “Is thy work hard? set a harder resolution against it; for there is nothing so hard that cannot be cut with something harder still.”

3. To labour with non-success, and to wait, is hard work. It is a grand thing for a Christian to continue patiently in well-doing.

II. Applicable to the cause of God in the world--to the Church. What power, however like to iron, shall suffice to break the kingdom of Jesus, which is comparable to steel?

1. We hear it said that Romanism will again vanquish England; that the Gospel light, which Latimer helped to kindle, will be extinguished. Atrocious nonsense, if not partial blasphemy. If this thing were of men, it would come to nought; but if it be of God, who shall overthrow it?

2. Others foretell the triumph of infidelity. That the gates of hell are to prevail against the Church; that the pleasure of the Lord is not to prosper in His hand. Who but a lying spirit would thus lay low the faith and confidence of God’s people?

III. Apply the principle to the self-righteous efforts which men make for their own salvation.

1. The bonds of guilt are not to be snapped by a merely human power.

2. Yet that were an easy task compared with a man renewing his own heart.

3. Do you think you can force your way to heaven by ceremony? Come, sinner, with thy fetters; lay thy wrist at the cross foot, where Christ can break the iron at once.

IV. Applicable to all persons who are making self-reliant efforts for the good of others.

1. Our preaching--we try to make it forcible--how powerless it is of itself! We plead, reason, seek goodly words, etc., but the northern iron and steel remain immovable. Though all the apostles reasoned with them, they would turn a deaf ear.

2. The best adapted means cannot succeed. A mother’s tears, as she spoke to you of Jesus; the pleadings of a grey-headed father over you--no power to change your heart! The Gospel, though put to you very tenderly by those you love best, leaves you unsaved still! You have been sick, near death, within an inch of doom; yet even the judgments of God have not aroused you.

V. This text has a very solemn application to all those who are rebels against God. Fight against God, would you? Measure your adversary, I charge you. The wax is about to wrestle with the flame, the tow to contend with the fire. (C. H. Spurgeon.)

Nothing more to be done

It is impossible to explain these words to the satisfaction of all. The general explanation, according to a large consensus of opinion, is that the prayer of the prophet cannot break the inflexible purpose of Jehovah. Jeremiah is still concerned for his countrymen, and he will still pray, though he has been told that if the mightiest intercessors that ever lived were to lift up their heads in devoutest argument they would not be listened to, for heaven was offended, and mighty in just indignation. Now the question is put, not by Jeremiah, but by another: “Shall iron break the northern iron and the steel?” Is there any iron in the south that can stand against the iron of the north? Has not the iron of the north been proved in a thousand controversies, and has it ever failed t Who will smite that northern iron with straw? Who will break it with a weapon of wood? Who will set his own frail hand against an instrument so tremendous? The argument, then, would seem to be--Why pray to me for these people? It is as iron applied to the iron of the north, which has been seen to fail in innumerable instances: all the prayers that can now be offered to heaven would be broken upon the threshold of that sanctuary and fall back in fragments upon the weary intercessor; the day has closed, the door is shut, the offended angel of grace has flown away on eagle pinions, and the sister angel of mercy can no longer be found: pray no more for Jerusalem. Thus the Lord dramatically represents Himself; and in all this dramatic reply to the interrogations and pleadings of earth there is a great principle indicated; that principle is that the day closes--“My Spirit shall not always strive with men.” These are awful words. If a man had invented them, we should have denied their truthfulness and their force; but when we hear them as from above we confirm them, we say, It is right, we do not deserve to be heard; if we had to assign ourselves to a fate, we dare not plant ha the wilderness of our solitude one single flower; we have done the things we ought not to have done, we have left undone the things we ought to have done; all we like sheep have gone astray, we have turned everyone to his own way.
