(2) Without that redemption no man could have been saved, nor could the angels have continued in a state of integrity. It shall be told first what redemption is. To redeem means to liberate from damnation,
to deliver from eternal death, to rescue from hell, and to release from the hand of the devil the captive and the bound. This the Lord did by subjugating the hells and establishing a new heaven.
Man could have been saved in no other way, for the reason that the spiritual world and the natural are so closely connected that they cannot by any means be separated. This connection is especially
in the interiors of men, which are called their souls and minds, the interiors of the good being connected with the souls and minds of angels, and of the wicked with the souls and minds of infernal spirits.
This union is such that if angels and spirits were taken away from man he would drop dead as a log. In like manner angels and spirits could not continue to exist if men were taken away from under
them. This makes clear why redemption was effected in the spiritual world, and why it was necessary that heaven and hell should be reduced to order before a church could be established on earth. That
this is so is very evident from the Apocalypse, where it is said that after the new heaven had been formed, the New Jerusalem, which is the New Church, descended from it (Rev. 21:1-2).
