Apocalypse Revealed #19
19. Who loves us and washes us from our sins in His blood. This symbolically means, who out of love and mercy reforms and regenerates people by His Divine truths drawn from the Word.
It is apparent that to wash us from our sins is to purify us from evils, thus to reform and regenerate, for regeneration is a spiritual washing. However, "His blood" does not mean the suffering of the cross, as many believe, but the Divine truth emanating from Him, as can be seen from many passages in the Word, which it would be too tedious to present in their entirety here. We will present them in nos. 379 and 684 below. In the meantime, see what we have said and shown regarding the symbolic meaning of the Lord's blood and flesh in the Holy Supper, in The New Jerusalem and Its Heavenly Doctrine, (London, 1758), nos. 210-222, and in the same place regarding spiritual washing, which is regeneration, nos. 202-209.
Revelation 19:15
15
And out of his mouth goeth a sharp sword, that with it he should smite the nations: and he shall rule them with a rod of iron: and he treadeth the winepress of the fierceness and wrath of Almighty God.
