“The attainment of any object is conditioned upon knowledge, volition and action. Unless these three conditions are forthcoming, there is no execution or accomplishment. In the erection of a house it is first necessary to know the ground, and design the house suitable for it; second, to obtain the means or funds necessary for the construction; third, actually to build it. Therefore, a power is needed to carry out and execute what is known and admitted to be the remedy for human conditions—namely, the unification of mankind.“

– ‘Abdu’l-Bahá, The Promulgation of Universal Peace
