Emanuel Swedenborg 
Heaven and its Wonders and Hell 

The Lord, speaking in the presence of His disciples of the consummation of the age, which is the final period of the church, says, near the end of what He foretells about its successive states in respect to love and faith:
Immediately after the tribulation of those days the sun shall be darkened, and the moon shall not give her light, and the stars shall fall from heaven, and the powers of the heavens shall be shaken. And then shall appear the sign of the Son of man in heaven; and then shall all the tribes of the earth mourn; and they shall see the Son of man coming in the clouds of heaven with power and great glory. And He shall send forth His angels with a trumpet and a great sound; and they shall gather together His elect from the four winds, from the end to end of the heavens (Matt. 24:29-31).
