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.
