When the masses of mankind are awakened and enter the Faith of God, a new process is set in motion and the growth of a new civilization begins. Witness the emergence of Christianity and of Islam. These masses are the rank and file, steeped in traditions of their own, but receptive to the new Word of God, by which, when they truly respond to it, they become so influenced as to transform those who come in contact with them.
