Consider the sun. Were it to say now,áullá "I am the sun of yesterday," it would speak the truth. And should it, bearing the sequence of time in mind, claim to be other than that sun, it still would speak the truth. In like manner, if it be said that all the days are but one and the same, it is correct and true. And if it be said, with respect to their particular names and designations, that they differ, that again is true. For though they are the same, yet one doth recognize in each a separate designation, a specific attribute, a particular character. Conceive accordingly the distinction, variation, and unity characteristic of the various Manifestations of holiness, that thou mayest comprehend the allusions made by the creator of all names and attributes to the mysteries of distinction and unity, and discover the answer to thy question as to why that everlasting Beauty should have, at sundry times, called Himself by different names and titles.--Kitáb-i-Íqán, 21-22.
Know that the return of Christ for a second time doth not mean what the people believe, but rather signifieth the One promised to come after Him. He shall come with the Kingdom of God and His Power which hath surrounded the world. This dominion is in the world of hearts and spirits, and not in that of matter; for the material world is not comparable to a single wing of a fly, in the sight of the Lord, wert thou of those who know! Verily Christ came with His Kingdom from the beginning which hath no beginning, and will come with His Kingdom to the eternity of eternities, inasmuch as in this sense "Christ" is an expression of the Divine Reality, the simple Essence and heavenly Entity, which hath no beginning nor ending. It hath appearance, arising, manifestation and setting in each of the cycles.
Christ and His apostles mentioned many signs which would distinguish the times of the "Return" of the Son of Man in the glory of the Father. Christ said:--
And when ye shall see Jerusalem compassed with armies, then know that the desolation thereof is nigh.... For these be the days of vengeance, that all things which are written may be fulfilled.... for there shall be great distress in the land, and wrath upon this people. And they shall fall by the edge of the sword, and shall be led away captive into all nations: and Jerusalem shall be trodden down by the Gentiles, until the times of the Gentiles shall be fulfilled.--Luke xxi, 20-24.
