But the Covenant of God and His Testament is a bounty to the righteous and a curse to the wicked.

‘Abdu’l-Bahá, Tablets of ‘Abdu’l-Bahá v2, p. 438

O thou whom my heart addresses! Know thou, verily, the Covenant is an Orb which shines and gleams forth unto the universe. Verily, its light will dispel darkness, its sea will cast out the thick foam of suspicions upon the shore of perdition.

‘Abdu’l-Bahá, Bahá’í Scriptures, p. 320

The Covenant of God ... is a lifeboat and ark of salvation.  All true followers of the Blessed Perfection are sheltered and protected in this ark.  Whoever leaves it, trusting in his own will and strength, will drown and be destroyed.

‘Abdu’l-Bahá, Daily Readings from the Bahá’í Teachings, p. 128

He feels you . . .  should devote particular attention to deepening the friends in the Covenant, which is the ark of safety for every believer.

Shoghi Effendi, Japan Will Turn Ablaze, p. 54

The Ark of Bahá’u’lláh's Covenant has, ever since those days, been steadily pursuing its course contemptuous of the storms of bitter misfortune that have raged, and which must continue to assail it, as it forges ahead towards the promised haven of undisturbed security and peace.

Shoghi Effendi, The World Order of Bahá’u’lláh, p. 84

The believers need to be deepened in their knowledge and appreciation of the Covenants of both Bahá’u’lláh and ‘Abdu’l-Bahá. This is the stronghold of the Faith of every Bahá’í, and that which enables him to withstand every test and the attacks of the enemies outside the Faith, and the far more dangerous, insidious, lukewarm people inside the Faith who have no real attachment to the Covenant, and consequently uphold the intellectual aspect of the teachings while at the same time undermining the spiritual foundation upon which the whole Cause of God rests. He feels you and your dear family should do all you can to teach the believers the Will and Testament to strengthen their understanding of its important provisions; for all the authority of the administrative bodies, as well as of the Guardian himself, is mainly derived from this tremendous document.
