Wert thou to open the heart of a single soul by helping him to embrace the Cause of Him Whom God shall make manifest, thine inmost being would be filled with the inspirations of that august Name. It devolveth upon you, therefore, to perform this task in the Days of Resurrection, inasmuch as most people are helpless, and wert thou to open their hearts and dispel their doubts, they would gain admittance into the Faith of God.
