As for those who believe not in the signs of God, or that they shall ever attain His Presence, these of My mercy shall despair, and these doth a grievous chastisement await.” And likewise He saith: “And they say, ‘What! when we shall have lain hidden in the earth, shall we become a new creation?’ Yea, they deny that they shall attain the Presence of their Lord.” And likewise He saith: “They truly doubt the Presence of their Lord. He, verily, overshadoweth all things.” And likewise He saith: “Verily, they who hope not to attain Our Presence, and find their satisfaction in this world’s life, and rest on it, and who of Our signs are heedless — these! their abode the fire, in recompense of their deeds!
Bahá’u’lláh, Epistle to the Son of the Wolf, p. 115
For they who turn away from their Lord in this day are in truth accounted amongst the dead, though to outward seeming they may walk upon the earth, amongst the deaf, though they may hear, and amongst the blind, though they may see, as hath been clearly stated by Him Who is the Lord of the Day of Reckoning: “Hearts have they with which they understand not, and eyes have they with which they see not….” They walk the edge of a treacherous bank and tread the brink of a fiery abyss. They partake not of the billows of this surging and treasure-laden Ocean, but disport themselves with their own idle words.
Bahá’u’lláh, Gems of Divine Mysteries, p. 48-49
Know thou for a certainty that whoso disbelieveth in God is neither trustworthy nor truthful. This, indeed, is the truth, the undoubted truth . . . Nothing whatever can deter such a man from evil, nothing can hinder him from betraying his neighbor, nothing can induce him to walk uprightly.
Bahá’u’lláh, Gleanings from the Writings of Bahá’u’lláh, p. 232-233
QUESTION: Is it permissible for a believer to marry an unbeliever?
ANSWER: Both taking and giving in marriage are permissible; thus did the Lord decree when He ascended the throne of bounteousness and grace.
Bahá’u’lláh, The Kitab-i-Aqdas, p. 131
The gates of Hell have opened wide to receive thee, O thou who hast turned away from thy Lord, the Unconstrained! Repair unto its fire, for it yearneth after thee.
Bahá’u’lláh, The Summons of the Lord of Hosts, p. 178
They that have disbelieved in God and rebelled against His sovereignty are the helpless victims of their corrupt inclinations and desires. These shall return to their abode in the fire of hell: wretched is the abode of the deniers!
Bahá’u’lláh, Gleanings from the Writings of Bahá’u’lláh, p. 284
This is the Day of God Himself; fear ye God and be not of them that have disbelieved in Him. Cast the idle tales behind your backs and behold My Revelation through Mine eyes. Unto this have ye been exhorted in heavenly Books and Scriptures, in the Scrolls and Tablets.
Bahá’u’lláh, Tablets of Bahá’u’lláh, p. 241-242
If thou remainest, at the moment of death, a disbeliever in the signs of thy Lord thou shalt surely enter the gates of hell, and none of the deeds thy hands have wrought will profit thee, nor shalt thou find a patron nor anyone to plead for thee.
The Báb, Selections from the Writings of the Báb, p. 19
One of the strangest things witnessed is that the materialists of today are proud of their natural instincts and bondage. They state that nothing is entitled to belief and acceptance except that which is sensible or tangible. By their own statements they are captives of nature, unconscious of the spiritual world, uninformed of the divine Kingdom and unaware of heavenly bestowals. If this be a virtue the animal has attained it to a superlative degree, for the animal is absolutely ignorant of the realm of spirit and out of touch with the inner world of conscious realization. The animal would agree with the materialist in denying the existence of that which transcends the senses. If we admit that being limited to the plane of the senses is a virtue the animal is indeed more virtuous than man, for it is entirely bereft of that which lies beyond, absolutely oblivious of the kingdom of God and its traces whereas God has deposited within the human creature an illimitable power by which he can rule the world of nature.

Question. — It is said in the Kitáb-i-Aqdas “…whoso is deprived thereof, hath gone astray, though he be the author of every righteous deed.” What is the meaning of this verse?
Answer. — This blessed verse means that the foundation of success and salvation is the knowledge of God, and that the results of the knowledge of God are the good actions which are the fruits of faith. If man has not this knowledge, he will be separated from God, and when this separation exists, good actions have not complete effect. This verse does not mean that the souls separated from God are equal, whether they perform good or bad actions. It signifies only that the foundation is to know God, and the good actions result from this knowledge. Nevertheless, it is certain that between the good, the sinners and the wicked who are veiled from God there is a difference. For the veiled one who has good principles and character deserves the pardon of God, while he who is a sinner, and has bad qualities and character, is deprived of the bounties and blessings of God. Herein lies the difference. Therefore, the blessed verse means that good actions alone, without the knowledge of God, cannot be the cause of eternal salvation, everlasting success, and prosperity, and entrance into the Kingdom of God.
‘Abdu’l-Bahá, Some Answered Questions, p. 237
The materialists and atheists declare that this order and symmetry is due to nature and its forces; that composition and decomposition which constitute life and existence are exigencies of nature; that man himself is an exigency of nature; that nature rules and governs creation; and that all existing things are captives of nature.
‘Abdu’l-Bahá, The Promulgation of Universal Peace, p. 81
The Prophets of God are the first Educators. They bestow universal education upon man and cause him to rise from the lowest levels of savagery to the highest pinnacles of spiritual development. The philosophers, too, are educators along lines of intellectual training. At most, they have only been able to educate themselves and a limited number about them, to improve their own morals and, so to speak, civilize themselves; but they have been incapable of universal education. They have failed to cause an advancement for any given nation from savagery to civilization.
‘Abdu’l-Bahá, The Promulgation of Universal Peace, p. 84-85
Many people whoso believe in God may be truthful and honest in a normal situation. But the real criterion of a man’s truthfulness and honesty is his attitude at the time of temptation. When severe tests and trials descend upon man, the only thing which keeps him truthful is his faith in God. If he does not believe in God, there is no motivation within him to resist temptation.
