Be pure, O people of God, be pure; be righteous, be righteous…. Say: O people of God! That which can ensure the victory of Him Who is the Eternal Truth, His hosts and helpers on earth, have been set down in the sacred Books and Scriptures, and are as clear and manifest as the sun. These hosts are such righteous deeds, such conduct and character, as are acceptable in His sight. Whoso ariseth, in this Day, to aid Our Cause, and summoneth to his assistance the hosts of a praiseworthy character and upright conduct, the influence flowing from such an action will, most certainly, be diffused throughout the whole world.
