A Revelation of the Holy Spirit | "God and Man Will Enter Into Rest Together Part One"

    Almighty God says, "As man lacks rest, so does God. When God once again enters into rest, man will also enter into rest. The life in rest is one without war, without filth, without persisting unrighteousness. This is to say that it lacks Satan’s harassment (here “Satan” refers to hostile forces), Satan’s corruption, as well as the invasion of any force opposed to God. Everything follows its own kind and worships the Lord of creation. Heaven and earth are entirely tranquil. This is humanity’s restful life. When God enters into rest, no more unrighteousness will persist upon the earth, and there will be no more invasion of any hostile forces. Humanity will also enter a new realm; he will no longer be a humanity corrupted by Satan, but rather a humanity that has been saved after having been corrupted by Satan."
