To be Faithful to “the Covenant and Testament of God” in this day requires that one’s “manners ..behavior..conduct ..morals, ..nature, and disposition” “reflect” such “attributes” of “sincerity ..faithfulness ..love ..honesty and fidelity …truthfulness and loving-kindness towards all the peoples of the world”

-- ye must conduct yourselves in such a manner that ye may stand out distinguished and brilliant as the sun among other souls. Should any one of you enter a city, he should become a centre of attraction by reason of his sincerity, his faithfulness and love, his honesty and fidelity, his truthfulness and loving-kindness towards all the peoples of the world, so that the people of that city may cry out and say: 'This man is unquestionably a Bahá'í, for his manners, his behaviour, his conduct, his morals, his nature, and disposition reflect the attributes of the Bahá'ís.' Not until ye attain this station can ye be said to have been faithful to the Covenant and Testament of God. For He hath, through irrefutable Texts, entered into a binding Covenant with us all, requiring us to act in accordance with His sacred instructions and counsels. (‘Abdu’l-Baha, ‘Selections from the Writings of 'Abdu'l-Bahá’; The Compilation of Compilations, vol. I, Trustworthiness: A Cardinal Bahá'í Virtue)

God is “immeasurably far and exalted” above any descriptions

Immeasurably exalted art Thou, O my God, above the endeavours of all beings and created things to praise Thee and recognize Thee. No creature can ever comprehend Thee as beseemeth the reality of Thy holy Being and no servant can ever worship Thee as is worthy of Thine unknowable Essence. Praise be unto Thee; too high is Thine exalted Self for any allusions proceeding from Thy creatures ever to gain access unto Thy presence.

Whenever, O my God, I soared into Thy holy atmosphere and attained the inmost spirit of prayerfulness unto Thee, I was led to recognize that Thou art inaccessible and that no mention of Thee can ever reach Thy transcendent court. Therefore I turn towards Thy Loved Ones -- They upon Whom Thou hast graciously conferred Thine Own station that They might manifest Thy love and Thy true knowledge. Bless Them then, O my God, with every distinction and goodly gift which Thy knowledge may reckon within the domain of Thy power.

We should view the teachings that God’s latest Manifestation, Baha’u’llah, has brought to humanity as “the light of this age and the spirit of this century”

The teachings of Bahá'u'lláh are the light of this age and the spirit of this century. Expound each of them at every gathering.

The first is investigation of truth,
The second, the oneness of mankind,
The third, universal peace,
The fourth, conformity between science and divine revelation,
The fifth, abandonment of racial, religious, worldly and political prejudices, prejudices which destroy the foundation of mankind.
The sixth is righteousness and justice,
The seventh, the betterment of morals and heavenly education,
The eighth, the equality of the two sexes,
The ninth, the diffusion of knowledge and education,
The tenth, economic questions, and so on and so forth.

Strive that souls may attain unto the light of guidance and hold fast unto the hem of Bahá'u'lláh. (‘Abdu'l-Baha, Selections from the Writings of Abdu'l-Baha)

We should purge our words from “idle fancies and worldly desires” and our deeds from “craftiness and suspicion”

Take heed that your words be purged from idle fancies and worldly desires and your deeds be cleansed from craftiness and suspicion. (Bahá'u'lláh, Tablets of Baha'u'lláh revealed after the Kitáb-i-Aqdas)

We should constantly strive to improve our character and provide service to others

Let each morn be better than its eve and each morrow richer than its yesterday. Man's merit lieth in service and virtue and not in the pageantry of wealth and riches. (Bahá'u'lláh, Tablets of Baha'u'lláh revealed after the Kitáb-i-Aqdas)

We should “bend every effort to banish ignorance from the earth.”

O peoples of the world! … bend every effort to banish ignorance from the earth. (Bahá'u'lláh, Tablets of Baha'u'lláh revealed after the Kitáb-i-Aqdas)

“we should not belittle anyone and call him ignorant”

In accordance with the divine teachings in this glorious dispensation we should not belittle anyone and call him ignorant, saying: 'You know not, but I know'. Rather, we should look upon others with respect, and when attempting to explain and demonstrate, we should speak as if we are investigating the truth, saying: 'Here these things are before us. Let us investigate to determine where and in what form the truth can be found.' The teacher should not consider himself as learned and others ignorant. Such a thought breedeth pride, and pride is not conducive to influence. The teacher should not see in himself any superiority; he should speak with the utmost kindliness, lowliness and humility, for such speech exerteth influence and educateth the souls. (‘Abdu'l-Baha, 'Selections from the Writings of ‘Abdu'l-Baha')

Each human being should independently examine God’s latest Teachings that have been brought to humanity by Baha’u’llah

...every great Cause in this world of existence findeth visible expression through three means: first, intention; second, confirmation; third, action. Today on this earth there are many souls who are promoters of peace and reconciliation and are longing for the realization of the oneness and unity of the world of humanity; but this intention needeth a dynamic power, so that it may become manifest in the world of being. In this day the divine instructions and lordly exhortations promulgate this most great aim, and the confirmations of the Kingdom also support and aid the realization of this intention. Therefore, although the combined forces and thoughts of the nations of the world cannot by themselves achieve this exalted purpose, the power of the Word of God penetrateth all things and the assistance of the divine Kingdom is continuous. Erelong it will become evident and clear that the ensign of the Most Great Peace is the teachings of Bahá'u'lláh, and the tent of union and harmony among nations is the Tabernacle of the divine Kingdom, for therein the intention, the power and the action, all three, are brought together. The realization of everything in the world of being dependeth upon these three elements. (‘Abdu’l-Baha, The Compilation of Compilations, vol. II, Peace)

We should “eliminate all forms of prejudice from our lives”

Bahá'u'lláh tells us that prejudice in its various forms destroys the edifice of humanity. We are adjured by the Divine Messenger to eliminate all forms of prejudice from our lives. Our outer lives must show forth our beliefs. .. Let us strive to blot out from our lives every last trace of prejudice -- racial, religious, political, economic, national, tribal, class, cultural, and that which is based on differences of education or age. (The Universal House of Justice, ‘Messages 1963 to 1986’)
