It is primarily through the potency of noble deeds and character, rather than by the power of exposition and proofs, that the friends of God should demonstrate to the world that what has been promised by God is bound to happen, that it is already taking place and that the divine glad-tidings are clear, evident and complete. For unless some illustrious souls step forth into the arena of service and shine out resplendent in the assemblage of men, the task of vindicating the truth of this Cause before the eyes of enlightened people would be formidable indeed. However, if the friends become embodiments of virtue and good character, words and arguments will be superfluous. Their very deeds will well serve as eloquent testimony, and their noble conduct will ensure the preservation, integrity and glory of the Cause of God.
