Why is God's wrath against the world system/Babylon so tremendous in Revelation 18:24?
Revelation 18:24 supplies the reason: in Babylon was found the blood of prophets, saints, and all who were slain on earth. This world system has persecuted, martyred, and murdered God's people for millennia, from ancient Babylon onward, so God's wrath against it is tremendous.
Les teaches that Revelation 18:24 is another reason God's wrath is so tremendous. The world system, extending back some 2,600 years to ancient Babylon and operating for the last 2,000 years, has persecuted, martyred, and murdered God's people. In Babylon was found the blood of prophets—Old Testament figures—and of saints, New Testament believers, and of all who were slain upon the earth. Earlier in the chapter, Les connects the merchants' sorceries to pharmakia, drugs, showing a tremendous end-time drug culture that deceives all nations.
And in her was found the blood of prophets, and of saints, and of all that were slain upon the earth.
