The wish of 'Abdu'l-Bahá, that which attracts His good pleasure and, indeed, His binding command, is that Bahá'ís, in all matters, even in small daily transactions and dealings with others, should act in accordance with the divine Teaching1s. He has commanded us not to be content with lowliness, humility and meekness, but rather to become manifestations of selflessness and utter nothingness. Of old, all have been exhorted to loyalty and fidelity, compassion and love; in this supreme Dispensation, the people of Bahá are called upon to sacrifice their very lives. Notice the extent to which the friends have been required in the Sacred Epistles and Tablets, as well as in our Beloved's Testament, to be righteous, well-wishing, forbearing, sanctified, pure, detached from all else save God, severed from the trappings of this world and adorned with the mantle of a goodly character and godly attributes.
First and foremost, one should use every possible means to purge one's heart and motives, otherwise, engaging in any form of enterprise would be futile. It is also essential to abstain from hypocrisy and blind imitation, inasmuch as their foul odour is soon detected by every man of understanding and wisdom. Moreover, the friends must observe the specific times for the remembrance of God, meditation, devotion and prayer, as it is highly unlikely, nay impossible, for any enterprise to prosper and develop when deprived of divine bestowals and confirmation. One can hardly imagine what a great influence genuine love, truthfulness and purity of motives exert on the souls of men. But these traits cannot be acquired by any believer unless he makes a daily effort to gain them... 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.
