‘And as regards their works and their thoughts, I am coming in order to collect all the nations and tongues together; and they will have to come and see my glory.’”​—Isaiah 66:15-18.

All the surrounding nations and language groups were obliged to witness this manifestation of the glory of Jehovah as the covenant-keeping God who does not lie. All of this solemnly reminds us that the same God has a controversy on a far larger scale with modern-day Christendom, which claims to have replaced ancient Israel as the people of Jehovah God. To his glory he will use his “sword” of vengeance to slay her utterly.
