When I was around the Baha'is, I read mostly Abdul Baha's stuff. Baha'u'llah was too flowery and Shoghi Effendi was too wordy.
Baha'u'llah...
Praise be to God, the Eternal that perisheth not, the Everlasting that declineth not, the Self-Subsisting that altereth not. He it is Who is transcendent in His sovereignty, Who is manifest through His signs, and is hidden through His mysteries. He it is at Whose bidding the standard of the Most Exalted Word hath been lifted up in the world of creation, and the banner of “He doeth whatsoever He willeth” raised amidst all peoples. He it is Who hath revealed His Cause for the guidance of His creatures, and sent down His verses to demonstrate His Proof and His Testimony, and embellished the preface of the Book of Man with the ornament of utterance through His saying: “The God of Mercy hath taught the Qur’án, hath created man, and taught him articulate speech.” No God is there but Him, the One, the Peerless, the Powerful, the Mighty, the Beneficent.
The light that is shed from the heaven of bounty, and the benediction that shineth from the dawning-place of the will of God, the Lord of the Kingdom of Names, rest upon Him Who is the Supreme Mediator, the Most Exalted Pen, Him Whom God hath made the Dawning-Place of His most excellent names and the Dayspring of His most exalted attributes. Through Him the light of unity hath shone forth above the horizon of the world, and the law of oneness hath been revealed amidst the nations, who, with radiant faces, have turned towards the Supreme Horizon, and acknowledged that which the Tongue of Utterance hath spoken in the kingdom of His knowledge: “Earth and heaven, glory and dominion, are God’s, the Omnipotent, the Almighty, the Lord of grace abounding!”
Give ear, O distinguished divine, unto the voice of this Wronged One. He verily, counselleth thee for the sake of God, and exhorteth thee unto that which will cause thee to draw nigh unto Him under all conditions. He, in truth, is the All-Possessing, the Exalted...
Shoghi Effendi...
How well we, the little band of His avowed supporters who lay claim to have recognized the Light that shone within Him, can still remember His repeated allusions, in the evening of His earthly life, to the tribulation and turmoil with which an unregenerate humanity was to be increasingly afflicted. How poignantly some of us can recall His pregnant remarks, in the presence of the pilgrims and visitors who thronged His doors on the morrow of the jubilant celebrations that greeted the termination of the World War—a war, which by the horrors it evoked, the losses it entailed and the complications it engendered, was destined to exert so far-reaching an influence on the fortunes of mankind. How serenely, yet how powerfully, He stressed the cruel deception which a Pact, hailed by peoples and nations as the embodiment of triumphant justice and the unfailing instrument of an abiding peace, held in store for an unrepented humanity. Peace, Peace, how often we heard Him remark, the lips of potentates and peoples unceasingly proclaim, whereas the fire of unquenched hatreds still smoulders in their hearts. How often we heard Him raise His voice, whilst the tumult of triumphant enthusiasm was still at its height and long before the faintest misgivings could have been felt or expressed, confidently declaring that the Document, extolled as the Charter of a liberated humanity, contained within itself seeds of such bitter deception as would further enslave the world. How abundant are now the evidences that attest the perspicacity of His unerring judgment!
