Only one thing remains to be said as to the process by which the radiant dream of the prophet is to be fulfilled. When there has come a profound revival of spiritual religion, and, consequently, a loftier and more exacting moral standard, there will be a wonderful conversion of destructive forces in the personal and national life. "They shall beat their swords into ploughshares and their spears into pruning-hooks." I want you carefully to notice that the sword is not to be destroyed; it is to be transformed; it is to become a ploughshare. The spear is not to be broken and thrown away; it is to be converted into a pruning-hook. That is to say, the rudely destructive energies in human life are to be changed into constructive energies. What was darkly negative is to become brightly positive. The martial is to be transformed into the pastoral. The rude implement of slaughter is to become the breaker of the earth-clod or the helpful friend of the vine. "They shall beat their swords into ploughshares and their spears into pruning-hooks." After the first historic siege of Antwerp, the cannon balls were taken and converted into church bells; and may the gracious and holy Lord grant that there may speedily come such a transformation in modern Antwerp, when all the ministers of carnage shall be changed into sweet and sacred ministers of worship and devotion! But now, if swords are to be beaten into ploughshares and spears into pruning-hooks, where must that work begin? It must begin in the individual heart. We are never going to get the swords out of the nations until we have got them out of the hearts. There is a sword in the heart, a cruel sword, a minister of destruction. There is a sword in the German heart, and a sword in the English heart, and a sword in the American heart, and that sword has got to be transformed before the material sword can become a ploughshare of the field! We are all familiar with our own swords; perhaps I had better say, we are all acquainted with one another's swords. There is the sword of ill-will. There is the spear of deadly gossip. There is the sword of evil prejudice. There is the spear of petty spite and contempt. Yea, surely there is a sordid armoury in the soul. And this has to be converted into a tool-house of a noble Christian culture before the material armouries can be emptied and the sound of war is heard no more.
