In many cases the literal fulfillment of these prophecies in the outward sense would be áulláabsurd or impossible; for example, the moon being turned into blood or the stars falling upon the earth. The least of the visible stars is many thousand times larger than the earth, and were one to fall on the earth there would be no earth left for another to fall on! In other cases, however, there is a material as well as a spiritual fulfillment. For example, the Holy Land did literally become desert and desolate during many centuries, as foretold by the prophets, but already, in the Day of Resurrection, it is beginning to "rejoice and blossom as the rose," as Isaiah foretold. Prosperous colonies are being started, the land is being irrigated and cultivated, and vineyards, olive groves and gardens are flourishing where half a century ago there was only sandy waste. Doubtless when men beat their swords into ploughshares and their spears into pruning hooks, wildernesses and deserts in all parts of the world will be reclaimed; the scorching winds and sandstorms that blow from these deserts, and make life in their neighborhood well-nigh intolerable, will be things of the past; the climate of the whole earth will become milder and more equable; cities will no longer defile the air with smoke and poisonous fumes, and even in the outward, material sense there will be "new heavens and a new earth."
As to the manner of His coming at the end of the age, Christ said:--
And they shall see the Son of man coming in the clouds of heaven with power and great glory. And he shall send his angels with a great sound of a trumpet.... then shall he sit upon the throne of his glory: And before him shall be gathered all nations: and he shall separate them one from another, as a shepherd divideth his sheep from the goats.--Matt. xxiv, 30-31; xxv, 31-32.
Regarding these and similar passages Bahá'u'lláh writes in the Book of Íqán:--
... The term "heaven" denoteth loftiness and exaltation, inasmuch as it is the seat of the revelation of those Manifestations of Holiness, the Day-springs of ancient glory. These ancient Beings, though delivered from the womb of their mother, have in reality descended from the heaven of the will of God. Though they be dwelling on this earth, yet their true habitations are the retreats of glory in the realms above. Whilst walking amongst mortals, they soar in the heaven of the divine presence. Without feet they tread the path of the spirit, and without wings they rise unto the exalted heights of divine unity. With every fleeting breath they cover the immensity
