The world is keeping together today because of the existence of these institutions.

The other thing is the building of the institutions of the Faith. The institutions of the faith which we are building now, the local assemblies and the national assemblies, these are the instruments for the future of mankind, the institutions for the future of mankind. We may not realize this yet ourselves because we are so much in the early days of the Faith and these institutions are so weak that we may not ever think probably that, "Oh, this Local Spiritual Assembly one day is going to become the House of Justice for this town." The House of Justice, who knows? Maybe it will become something like the government of this town, but whatever it is - Hello! Beautiful little boy. Very nice. - These local spiritual assemblies one day become Houses of Justice for mankind, for the people of this town. And we may not realize this, but at this moment that we are talking about it, we are entering into a very critical age, critical time in the history of mankind. A time which we talked about again this morning is filled with perils and with dangers and with sufferings, with tribulations, calamities, and the only thing which mankind will have when the world is really has tasted the agony of this whole calamities which has to come are these institutions we are building. There is nothing else which will be left which mankind can really have turned to which would save it. And even now as we stand here, if it wasn't for the institutions of the Faith or the new life which Bahá’u’lláh has breathed into the world of man, the world would not be together. The world is keeping together today because of the existence of these institutions. It's because of the House of Justice that the world is now exist the way it is and can exist.... We must believe in these things. We are not building these assemblies for fun. There's no fun in that.
