Next World

And now concerning thy question regarding the soul of man and its survival after death. Know thou of a truth that the soul, after its separation from the body, will continue to progress until it attaineth the presence of God, in a state and condition which neither the revolution of ages and centuries, nor the changes and chances of this world, can alter. It will endure as long as the Kingdom of God, His sovereignty, His dominion and power will endure. It will manifest the signs of God and His attributes, and will reveal His loving kindness and bounty.

Bahá’u’lláh, Gleanings from the Writings of Bahá’u’lláh, p. 155-156

Blessed is the soul which, at the hour of its separation from the body, is sanctified from the vain imaginings of the peoples of the world. Such a soul liveth and moveth in accordance with the Will of its Creator, and entereth the all-highest Paradise. The Maids of Heaven, inmates of the loftiest mansions, will circle around it, and the Prophets of God and His chosen ones will seek its companionship. With them that soul will freely converse, and will recount unto them that which it hath been made to endure in the path of God, the Lord of all worlds.

Bahá’u’lláh, Gleanings from the Writings of Bahá’u’lláh, p. 155

If any man be told that which hath been ordained for such a soul in the worlds of God, the Lord of the throne on high and of earth below, his whole being will instantly blaze out in his great longing to attain that most exalted, that sanctified and resplendent station.

Bahá’u’lláh, Gleanings from the Writings of Bahá’u’lláh, p. 156

It is clear and evident that all men shall, after their physical death, estimate the worth of their deeds, and realize all that their hands have wrought. I swear by the Day Star that shineth above the horizon of Divine power! They that are the followers of the one true God shall, the moment they depart out of this life, experience such joy and gladness as would be impossible to describe, while they that live in error shall be seized with such fear and trembling, and shall be filled with such consternation, as nothing can exceed. Well is it with him that hath quaffed the choice and incorruptible wine of faith through the gracious favor and the manifold bounties of Him Who is the Lord of all Faiths.

Bahá’u’lláh, Gleanings from the Writings of Bahá’u’lláh, p. 171

Learn well this Tablet, O Ahmad. Chant it during thy days and withhold not thyself therefrom. For verily, God hath ordained for the one who chants it, the reward of a hundred martyrs and a service in both worlds. These favors have We bestowed upon thee as a bounty on Our part and a mercy from Our presence, that thou mayest be of those who are grateful.

Bahá’u’lláh, Tablet of Ahmad, Bahá’í Prayers, p. 211

The "life to come," on the other hand, signifieth the things that give you a safe approach to God, the All-Glorious, the Incomparable.
