They go from strength to strength.' I do not know whether the Psalmist means to use that word' strength' in the significance which it also has in old English, of a fortified place, so that the metaphor would be that from one camp of security, one fortress to another, they journey safe always, because of their protection; or whether he means to use it rather in its plain and simple sense, according to which the significance would be that these happy pilgrims do not get worn out on the journey, as is the wont of men that set out, for instance, from some far corner of India to Mecca, and come in battered and travel-stained, and half dead with their privations, but that the further they go the stronger they become; and on the road gain more vigour than they could ever have gained by ease and indulgence in their homes. But, whichever of these two meanings we may be disposed to adopt, the great thought that comes out of both of them is identical, viz, that this is one of the distinguishing joys of a Christian career of pressing forward to closer communion and conformity with our Lord and Master, in whom God is manifested--viz, that we grow day by day in strength, and that effort does not weaken, but invigorates.
And now I have to put a very plain question. Is that growing strength anything like the general characteristic of us professing Christians? I wonder how many people there are listening to me now that have been members of Christian churches for half a century almost, but are not a bit better than they were away back in the years that they have almost forgotten? I wonder in how many of our cases there has been an arrested development, like that which you will sometimes see in deformed people, the lower limbs all but atrophied? I wonder how many of us are babes of forty years old, and from how many of our minds the very conception of continual growth, as an essential of Christian life, has altogether vanished? Brother! are you any further than you were ten years ago?
I remember once, long ago, when I was on board a sailing ship, that we had baffling winds as we tried to run up the coast; and morning after morning for a week we used to come up on deck, and there were the same windmill, and the same church-tower that we had seen last night, and the night before and the night before that. That is the sort of voyage that a great many of you Christian people are making. There may be motion; there is no progress. Round and round and round you go. That is not the way to get to Zion. They go from strength to strength,' and unless you are doing that, you know little about the blessedness of the pilgrim heart.
