---

Your feet shod with the preparation of the gospel of peace.' -- Eph. vi.15.

Paul drew the first draft of this picture of the Christian armour in his first letter. It is a finished picture here. One can fancy that the Roman soldier to whom he was chained in his captivity, whilst this letter was being written, unconsciously sat for his likeness, and that each piece of his accoutrements was seized in succession by the Apostle's imagination and turned to a Christian use. It is worth noticing that there is only one offensive weapon mentioned -- 'the sword of the Spirit.' All the rest are defensive -- helmet, breastplate, shield, girdle, and shoes. That is to say, the main part of our warfare consists in defence, in resistance, and in keeping what we have, in spite of everybody, men and devils, who attempt to take it from us. 'Hold fast that thou hast; let no man take thy crown.'

Now, it seems to me that the ordinary reader does not quite grasp the meaning of our text, and that it would be more intelligible if, instead of 'preparation,' which means the process of getting a thing ready, we read 'preparedness,' which means the state of mind of the man who is ready. Then we have to notice that the little word 'of' does duty to express two different relations, in the two instances of its use here. In the first case -- 'the preparedness of the Gospel' -- it states the origin of the thing in question. That condition of being ready comes from the good news of Christ. In the second case -- 'the Gospel of peace' -- it states the result of the thing in question. The good news of Christ gives peace. So, taking the whole clause, we may paraphrase it by saying that the preparedness of spirit, the alacrity which comes from the possession of a Gospel that sheds a calm over the heart and brings a man into peace with God, is what the Apostle thinks is like the heavy hob-nailed boots that the legionaries wore, by which they could stand firm, whatever came against them.

I. The first thing that I would notice here is that the Gospel brings peace.

I suppose that there was ringing in Paul's head some echoes of the music of Isaiah's words, 'How beautiful upon the mountains are the feet of Him that bringeth good tidings, that publisheth peace, that bringeth good tidings of good!' But there is a great deal more than an unconscious quotation of ancient words here; for in Paul's thought, the one power which brings a man into harmony with the universe and to peace with himself, is the power which proclaims that God is at peace with him. And Jesus Christ is our peace, because He has swept away the root and bitter fountain of all the disquiet of men's hearts, and all their chafing at providences -- the consciousness that there is discord between themselves and God. The Gospel brings peace in the deepest sense of that word, and, primarily, peace with God, from out of which all other kinds of tranquillity and heart-repose do come -- and they come from nothing besides.

But what strikes me most here is not so much the allusion to the blessed truth that was believed and experienced by these Ephesian Christians, that the Gospel brought peace, and was the only thing that did, as the singular emergence of that idea that the Gospel was a peace-bringing power, in the midst of this picture of fighting. Yes, it brings both. It brings us peace first, and then it says to us, 'Now, having got peace in your heart, because peace with God, go out and fight to keep it.' For, if we are warring with the devil we are at peace with God; and if we are at peace with the devil we are warring with God. So the two states of peace and war go together. There is no real peace which has not conflict in it, and the Gospel is 'the Gospel of peace,' precisely because it enlists us in Christ's army and sends us out to fight Christ's battles.

So, then, dear brother, the only way to realise and preserve 'the peace of God which passes understanding' is to fling ourselves manfully into the fight to which all Christ's soldiers are pledged and bound. The two conditions, though they seem to be opposite, will unite; for this is the paradox of the Christian life, that in all regions it makes compatible apparently incompatible and contradictory emotions. 'As sorrowful' -- and Paul might have said 'therefore' instead of 'yet' -- 'as sorrowful yet always rejoicing; as having nothing yet' -- therefore -- 'possessing all things'; as in the thick of the fight, and yet kept in perfect peace, because the soul is stayed on God. The peace that comes from friendship with Him, the peace that fills a heart tranquil because satisfied, the peace that soothes a conscience emptied of all poison and robbed of all its sting, the peace that abides because, on all the horizon in front of us nothing can be seen that we need to be afraid of -- that peace is the peace which the Gospel brings, and it is realised in warfare and is consistent with it. All the armies of the world may camp round the fortress, and the hurtling noise of battle may be loud in the plains, but up upon the impregnable cliff crowned by its battlements there is a central citadel, with a chapel in the heart of it; and to the worshippers there none of the noise ever penetrates. The Gospel which laps us in peace and puts it in our hearts makes us soldiers.

II. Further, this Gospel of peace will prepare us for the march.

A wise general looks after his soldiers' boots. If they give out, nothing else is of much use. The roads are very rough and very long, and there need to be strong soles and well-sewed uppers, and they will be none the worse for a bit of iron on the heels and the toes, in order that they may not wear out in the midst of the campaign. 'Thy shoes shall be iron and brass,' and these metals are harder than any of the rock that you will have to clamber over. Which being translated into plain fact is just this -- a tranquil heart in amity with God is ready for all the road, is likely to make progress, and is fit for anything that it may be called to do.

A calm heart makes a light foot; and he who is living at peace with God, and with all disturbance within hushed to rest, will, for one thing, be able to see what his duty is. He will see his way as far as is needful for the moment. That is more than a good many of us can do when our eyes get confused, because our hearts are beating so loudly and fast, and our own wishes come in to hide from us God's will. But if we are weaned from ourselves, as we shall be if we are living in possession of the peace of God which passes understanding, the atmosphere will be transparent, as it is on some of the calm last days of autumn, and we shall see far ahead and know where we ought to go.

The quiet heart will be able to fling its whole strength into its work. And that is what troubled hearts never can do, for half their energy is taken up in steadying or quieting themselves, or is dissipated in going after a hundred other things. But when we are wholly engaged in quiet fellowship with Jesus Christ we have the whole of our energies at our command, and can fling ourselves wholly into our work for Him. The steam-engine is said to be a very imperfect machine which wastes more power than it utilises. That is true of a great many Christian people; they have the power, but they are so far away from that deep sense of tranquillity with God, of which my text speaks, that they waste much of the power that they have. And if we are to have for our motto 'Always Ready.' as an old Scottish family has, the only way to secure that is by having 'our feet shod with the preparedness' that comes from the Gospel that brings us peace. Brethren, duty that is done reluctantly, with hesitation, is not done. We must fling ourselves into the work gladly and be always 'ready for all Thy perfect will.'

There was an English commander, who died some years ago, who was sent for to the Horse Guards one day and asked, 'How long will it take for you to be ready to go to Scinde?' 'Half an hour,' said he; and in three-quarters he was in the train, on his road to reconquer a kingdom. That is how we ought to be; but we never shall be, unless we live habitually in tranquil communion with God, and in the full faith that we are at peace with Him through the blood of His Son. A quiet heart makes us ready for duty.

III. Again, the Gospel of peace prepares us for combat.

In ancient warfare battles were lost or won very largely according to the weight of the masses of men that were hurled against each other; and the heavier men, with the firmer footing, were likely to be the victors. Our modern scientific way of fighting is different from that. But in the old time the one thing needful was that a man should stand firm and resist the shock of the enemies as they rushed upon him. Unless our footing is good we shall be tumbled over by the onset of some unexpected antagonist. And for good footing there are two things necessary. One is a good, solid piece of ground to stand on, that is not slippery nor muddy, and the other is a good, strong pair of soldier's boots, that will take hold on the ground and help the wearer to steady himself. Christ has set our feet on the rock, and so the first requisite is secured. If we, for our part, will keep near to that Gospel which brings peace into our hearts, the peace that it brings will make us able to stand and bear unmoved any force that may be hurled against us. If we are to be 'steadfast, unmovable,' we can only be so when our feet are shod with the preparedness of the Gospel of peace.

The most of your temptations, most of the things that would pluck you away from Jesus Christ, and upset you in your standing will come down upon you unexpectedly. Nothing happens in this world except the unexpected; and it is the sudden assaults that we were not looking for that work most disastrously against us. A man may be aware of some special weakness in his character, and have given himself carefully and patiently to try to fortify himself against it, and, lo! all at once a temptation springs up from the opposite side; the enemy was lying in hiding there, and whilst his face was turned to fight with one foe, a foe that he knew nothing about came storming behind him. There is only one way to stand, and that is not merely by cultivating careful watchfulness against our own weaknesses, but by keeping fast hold of Jesus Christ manifested to us in His Gospel. Then the peace that comes from that communion will itself guard us.

You remember what Paul says in one of his other letters, where he has the same beautiful blending together of the two ideas of peace and warfare: 'The peace of God, which passeth all understanding, shall garrison your hearts and minds in Christ Jesus.' It will be, as it were, an armed force within your heart which will repel all antagonism, and will enable you to abide in that Christ, through whom and in whom alone all peace comes. So, because we are thus liable to be overwhelmed by a sudden rush of unexpected temptation, and surprised into a sin before we know where we are, let us keep fast hold by that Gospel which brings peace, which will give us steadfastness, however suddenly the masked battery may begin to play upon us, and the foe may steal out of his ambush and make a rush against our unprotectedness. That is the only way, as I think, by which we can walk scatheless through the world.

Now, dear brethren, remember that this text is part of a commandment. We are to put on the shoes. How is that to be done? By a very simple way: a way which, I am afraid, a great many Christian people do not practise with anything like the constancy that they ought. For it is the Gospel that brings the peace, and if its peace brings the preparedness, then the way to get the preparedness is by soaking our minds and hearts in the Gospel of Jesus Christ.

You hear a good deal nowadays about deepening the spiritual life, and people hold conventions for the purpose. All right; I have not a word to say against that. But, conventions or no conventions, there is only one thing that deepens the spiritual life, and that is keeping near the Christ from whom all the fulness of the spiritual life flows. If we will hold fast by our Gospel, and let its peace lie upon our minds, as the negative of a photograph lies upon the paper that it is to be printed upon, until the image of Jesus Christ Himself is reproduced in us, then we may laugh at temptation. For there will be no temptation when the heart is full of Him, and there will be no sense of surrendering anything that we wish to keep when the superior sweetness of His grace fills our souls. It is empty vessels into which poison can be poured. If the vessel is full there will be no room for it. Get your hearts and minds filled with the wine of the kingdom, and the devil's venom of temptation will have no space to get in. It is well to resist temptation; it is better to be lifted above it, so that it ceases to tempt. And the one way to secure that is to live near Jesus Christ, and let the Gospel of His grace take up more of our thoughts and more of our affections than it has done in the past. Then we shall realise the fulfilment of the promise: 'He will not suffer thy foot to be moved.'
