The vision of community should fully embrace its children and youth

It is imperative… that… definite steps be taken to ensure that the vision of the community fully embraces its younger members. The education of children, an obligation enjoined on both parents and institutions, requires special emphasis so as to become thoroughly integrated into the process of community development. 

- The Universal House of Justice  (From a message dated 26 November 1999) 

Each human being has two powers and two aspects of development - material & spiritual

Man has two powers; and his development, two aspects. One power is connected with the material world, and by it he is capable of material advancement. The other power is spiritual, and through its development his inner, potential nature is awakened. These powers are like two wings. Both must be developed, for flight is impossible with one wing. Praise be to God! Material advancement has been evident in the world, but there is need of spiritual advancement in like proportion. We must strive unceasingly and without rest to accomplish the development of the spiritual nature in man, and endeavor with tireless energy to advance humanity toward the nobility of its true and intended station. For the body of man is accidental; it is of no importance. The time of its disintegration will inevitably come. But the spirit of man is essential and, therefore, eternal. It is a divine bounty. It is the effulgence of the Sun of Reality and, therefore, of greater importance than the physical body. 

- ‘Abdu’l-Baha  (From a talk, 25 April, 1912, Washington, D.C.; ‘The Promulgation of Universal Peace: Talks Delivered by 'Abdu'l-Bahá during His Visit to the United States and Canada in 1912’)

The “attributes of the people of faith”

…the attributes of the people of faith are justice and fair-mindedness; forbearance and compassion and generosity; consideration for others; candor, trustworthiness, and loyalty; love and loving-kindness; devotion and determination and humanity. 

- ‘Abdu'l-Baha  (‘The Secret of Divine Civilization’)

In return for all the care and hardship that one’s parent go through, children should “make charitable contributions and perform good works in their name, and implore pardon and forgiveness for their souls”

...parents endure the greatest toil and trouble for their children, and often, by the time the latter have reached the age of maturity, the former have hastened to the world beyond. Rarely do the mother and father enjoy in this world the rewards of all the pain and trouble they have endured for their children. The children must therefore, in return for this pain and trouble, make charitable contributions and perform good works in their name, and implore pardon and forgiveness for their souls. 

- ‘Abdu’l-Baha  (Table talks in Akka, authenticated by ‘Abdu’l-Baha; ‘Some Answered Questions’ – 2014 revised translation by the Baha’i World Center)

We shouldn’t allow anything to “intervene” between us and God

Should a man wish to adorn himself with the ornaments of the earth, to wear its apparels, or partake of the benefits it can bestow, no harm can befall him, if he alloweth nothing whatever to intervene between him and God, for God hath ordained every good thing, whether created in the heavens or in the earth, for such of His servants as truly believe in Him. Eat ye, O people, of the good things which God hath allowed you, and deprive not yourselves from His wondrous bounties. Render thanks and praise unto Him, and be of them that are truly thankful. 

- Baha’u’llah  ('Gleanings from the Writings of Baha’u’llah’; The Compilation of Compilations, vol. I, Conservation of the Earth's Resources)

We should view the world as “one homeland and one habitation”

This span of earth is but one homeland and one habitation. It behoveth you to abandon vainglory which causeth alienation and to set your hearts on whatever will ensure harmony. In the estimation of the people of Bahá man’s glory lieth in his knowledge, his upright conduct, his praiseworthy character, his wisdom, and not in his nationality or rank. 

- Baha’u’llah  (‘Tablets of Baha’u’llah revealed after the Kitab-i-Aqdas)

Involvement in the society

Be anxiously concerned with the needs of the age ye live in, and centre your deliberations on its exigencies and requirements. 

- Baha’u’llah  (‘The Tabernacle of Unity’) 

Each human being has two natures or aspects – God’s Teachings brought to humanity through His various Prophets are to help us conquer our animal nature.

Man has two aspects or natures - merciful or divine and an animal aspect. The merciful aspect is peace, happiness, love and faithfulness. But the animal aspect is strife, discord, war and battle. If the animal aspect dominates in man, he becomes lower than an animal. If the divine aspect dominates, he becomes an angel of the Lord. The teachings of the Prophets were for this: that the animal aspect may be conquered, so that the souls that are captives of nature may be saved and the heavenly aspect may dominate. That divine aspect consists of the outpouring of the Holy Spirit. It consists of 'the second birth.' He who possesses that aspect is a well-wisher of all; he is kind to all the creatures; he has no bitterness toward any creed, and he shuns no religion. 

- ‘Abdu’l-Baha  (From a talk given at the Universalist Church in Washington DC, April 21, 1912; Star of the West, vol.19, no. 3, June 1928)

One should never consider himself/herself greater than others

…the first self-conceited one was Satan. A man must never consider himself greater than others. Rather, he must always be humble and self-effacing. The bird, as long as it sees itself at a low level, is given impetus to soar and progress; but the moment it fancies itself high in the air, it begins to descend. 

- 'Abdu'l-Baha  (Words of ‘Abdu’l-Baha, 24 Denver 1912, Lincoln, USA; ‘Mahmud’s Diary’)
