For just as the effects and the fruitage of the uterine life are not to be found in that dark and narrow place, and only when the child is transferred to this wide earth do the benefits and uses of growth and development in that previous world become revealed—so likewise reward and punishment, heaven and hell, requital and retribution for actions done in this present life, will stand revealed in that other world beyond. And just as, if human life in the womb were limited to that uterine world, existence there would be nonsensical, irrelevant—so too if the life of this world, the deeds here done and their fruitage, did not come forth in the world beyond, the whole process would be irrational and foolish.
(‘Abdu’l-Bahá, Selections from the Writings of ‘Abdu’l-Bahá, p. 184)
In the matrix of the mother the unborn child was deprived and unconscious of the world of material existence, but after its birth it beheld the wonders and beauties of a new realm of life and being. In the world of the matrix it was utterly ignorant and unable to conceive of these new conditions, but after its transformation it discovers the radiant sun, trees, flowers and an infinite range of blessings and bounties awaiting it. Material development may be likened to the glass of a lamp, whereas divine virtues and spiritual susceptibilities are the light within the glass. The lamp chimney is worthless without the light; likewise, man in his material condition requires the radiance and vivification of the divine graces and merciful attributes. Without the presence of the Holy Spirit he is lifeless. Although physically and mentally alive, he is spiritually dead. Christ announced, “That which is born of the flesh is flesh; and that which is born of the Spirit is spirit,” meaning that man must be born again. As the babe is born into the light of this physical world, so must the physical and intellectual man be born into the light of the world of Divinity.
