I am going to tell you what I think then back it up with a quote because it expresses very well what I believe. The quote, or quotes if there are more than one that seems to fit, will not be from the Bible.
I think Atheists are going to get what they deserve just as much as Christians are going to get what they deserve. I think there are Atheists that are more Christian than many Christians and there are Christians who make many Atheists seem like saints by comparison. For me there is no question, no controversy. Heaven and Hell are not places but rather states of the soul. I firmly believe that when this life is over there will be Atheists who will be pleasantly surprised to find themselves in Heaven and Christians who will be shocked at finding themselves in Hell. But Heaven and Hell can also be right here on Earth.
When asked on one occasion: "What is a Bahá'í?" 'Abdu'l-Bahá replied: "To be a Bahá'í simply means to love all the world; to love humanity and try to serve it; to work for universal peace and universal brotherhood." On another occasion He defined a Bahá'í as "one endowed with all the perfections of man in activity." In one of His London talks He said that a man may be a Bahá'í even if He has never heard the name of Bahá'u'lláh. He added: --
The man who lives the life according to the teachings of Bahá'u'lláh is already a Bahá'í. On the other hand, a man may call himself a Bahá'í for fifty years, and if he does not live the life he is not a Bahá'í. An ugly man may call himself handsome, but he deceives no one, and a black man may call himself white, yet he deceives no one, not even himself.

The immortality of the spirit is mentioned in the Holy Books; it is the fundamental basis of the divine religions. Now punishments and rewards are said to be of two kinds. Firstly, the rewards and punishments of this life; secondly, those of the other world. But the paradise and hell of existence are found in all the worlds of God, whether in this world or in the spiritual heavenly worlds.
(Abdu'l-Baha, Baha'i World Faith - Abdu'l-Baha Section, p. 323)
The Jews await the Messiah, the Christians the return of Christ, the Moslems the Mahdi, the Buddhists the fifth Buddha, the Zoroastrians Shah Bahram, the Hindus the reincarnation of Krishna, and the Atheists - a better social organization! Baha'u'llah represents all these, and thus destroys the rivalries and the enmities of the different religions; reconciles them in their primitive purity, and frees them from the corruption of dogmas and rites. For the Baha'i Faith has no clergy, no religious ceremonial, no public prayers; its only dogma is belief in God and in his Manifestations (Zoroaster, Moses, Jesus, et al., Baha'u'llah).
