And so, dear brethren, if we think of all that is given to us in God's Gospel in the way of stimulus and encouragement, and exhortation, and actual communication of powers, we may calculate, from the abundance of the resources, how great will be the strain upon us before we come to the end, and our 'feet stand within thy gates, O Jerusalem.' Go into some of the great fortresses in continental countries, and you will find the store-rooms full of ammunition and provisions; bread enough and biscuits enough, as it seems, for half the country, laid up there, and a deep well somewhere or other in the courtyard. What does that mean? It means fighting, that is what it means. So if we are brought into this strong pavilion, so well provisioned, so massively fortified and defended, that means that we shall need all the strength that is to be found in those thick walls, and all the sustenance that is to be found in those gorged magazines, and all the refreshment that is to be drawn from that free, and full, and inexhaustible fountain, before the battle is over and the victory won. Depend upon it, the promise 'Thy shoes shall be iron and brass.' means, 'Thy road shall be rocky and flinty'; and so it is.
And yet, thank God! whilst it is true that it is very hard and very difficult for many of us, and hard and difficult--even if without the 'very'--for us all, it is also true that we have the adequate provision sufficient for all our necessities--and far more than sufficient! It is a poor compliment to the strength that He gives to us to say that it is enough to carry us through. God does not deal out His gifts to people with such an economical correspondence to necessities as that. There is always a wide margin. More than we can ask, more than we can think, more than we can need is given us.
If He were to deal with us as men often deal with one another, asking us, 'Well, how much do you want? cannot you do with a little less? there is the exact quantity that you need for your support'--if you got your bread by weight and your water by measure, it would be a very poor affair. See how He actually does--He says, 'Child, there is Mine own strength for you'; and we think that we honour Him when we say, 'God has given us enough for our necessities!' Rather the old word is always true: 'So they did eat and were filled; and they took up of the fragments that remained seven baskets-full,' and after they were satisfied and replete with the provision, there was more at the end than when they began.
That suggests another possible thought to be drawn from this promise, namely, that it assures not only of strength adequate to the difficulties and perils of the journey, but also of a strength which is not worn out by use.
The 'portion' of Asher was the rocky sea-coast. The sharp, jagged rocks would cut to pieces anything made of leather long before the day's march was over; but the travellers have their feet shod with metal, and the rocks which they have to stumble over will only strike fire from their shoes. They need not step timidly for fear of wearing them out; but, wherever they have to march, may go with full confidence that their shoeing will not fail them. A wise general looks after that part of his soldiers' outfit with special care, knowing that if _it_ gives out, all the rest is of no use. So our Captain provides us with an inexhaustible strength, to which we may fully trust. We shall not exhaust it by any demands that we can make upon it. We shall only brighten it up, like the nails in a well-used shoe, the heads of which are polished by stumbling and scrambling over rocky roads.
