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 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).

Emanuel Swedenborg (born Emanuel Swedberg; February 8, 1688-March 29, 1772) was a Swedish scientist, philosopher, Christian mystic, and theologian.

Swedenborg had a prolific career as an inventor and scientist. At the age of fifty-six he entered into a spiritual phase in which he experienced dreams and visions.

This culminated in a spiritual awakening, where he claimed he was appointed by the Lord to write a heavenly doctrine to reform Christianity.

He claimed that the Lord had opened his eyes, so that from then on he could freely visit heaven and hell, and talk with angels, demons, and other spirits.

For the remaining 28 years of his life, he wrote and published 18 theological works, of which the best known was Heaven and Hell (1758), and several unpublished theological works.
