"In the second Gospel, according to Mark, the Dove of holiness speaketh in such terms: “For in those days shall be affliction, such as was not from the beginning of the creation which God created unto this time, neither shall be.”⁷ And it singeth later with the same melodies as before, without change or alteration. God, verily, is a witness unto the truth of My words.

And in the third Gospel, according to Luke, it is recorded: “There shall be signs in the sun, and in the moon, and in the stars, and upon the earth distress of nations, with perplexity; the sea and the waves roaring; and the powers of heaven shall be shaken. And then shall they see the Son of man coming in a cloud with power and great glory. And when these things begin to come to pass, know that the kingdom of God hath drawn nigh.” ^8"
