Look at why the Prophets came... and with that in mind, why are we fighting?

Look how Abraham strove to bring faith and love among the people; how Moses tried to unite the people by sound laws; how the Lord Christ suffered unto death to bring the light of love and truth into a darkened world; how Muhammad sought to bring unity and peace between the various uncivilized tribes among whom he dwelt. And last of all, Baha’u’llah has suffered forty years for the same cause--the single noble purpose of spreading love among the children of men--and for the peace and unity of the world the Bab gave up his life.

'Abdu'l-Baha, Paris Talks, p. 171

To thank Him...

...Make ye a mighty effort, and choose for yourselves a noble goal. Through the power of faith, obey ye the teachings of God, and let all your actions conform to His laws. Read ye The Hidden Words, ponder the inner meanings thereof, act in accord therewith. Read, with close attention, the Tablets of Tarazat (Ornaments), Kalimat (Words of Paradise), Tajalliyat (Effulgences), Ishraqat (Splendours), and Bisharat (Glad Tidings), and rise up as ye are bidden in the heavenly teachings. Thus may each one of you be even as a candle casting its light, the centre of attraction wherever people come together; and from you, as from a bed of flowers, may sweet scents be shed.

'Abdu'l-Baha, Selections from the Writings of 'Abdu'l-Baha, p. 35

The First and Twin Duties

The first duty prescribed by God for His servants is the recognition of Him Who is the Dayspring of His Revelation and the Fountain of His laws, Who representeth the Godhead in both the Kingdom of His Cause and the world of creation.

Whoso achieveth this duty hath attained unto all good; and whoso is deprived thereof hath gone astray, though he be the author of every righteous deed.

It behoveth every one who reacheth this most sublime station, this summit of transcendent glory, to observe every ordinance of Him Who is the Desire of the world. These twin duties are inseparable. Neither is acceptable without the other. Thus hath it been decreed by Him Who is the Source of Divine inspiration.

Baha'u'llah, The Kitab-i-Aqdas, p. 19 paragraph 1

The Aqdas, the unerring Balance

Weigh not the Book of God with such standards and sciences as are current amongst you, for the Book itself is the unerring Balance established amongst men. In this most perfect Balance whatsoever the peoples and kindreds of the earth possess must be weighed, while the measure of its weight should be tested according to its own standard, did ye but know it.

Baha'u'llah, The Kitab-i-Aqdas, p. 56 paragraph 99
