"God hath prescribed unto every one the duty of teaching His Cause."

"God hath prescribed unto every one the duty of teaching His Cause. Whoever ariseth to discharge this duty, must needs, ere he proclaimeth His Message, adorn himself with the ornament of an upright and praiseworthy character, so that his words may attract the hearts of such as are receptive to his call. Without it, he can never hope to influence his hearers."
