There will be weeping and gnashing of teeth, when you see Abraham and Isaac and Jacob and all the prophets in the kingdom of God, and yourselves thrust out. - Luke 13: 28 NKJV
The WT loves to call themselves the "Israel of God". Ha. Jesus specifically targets these kinds of boasters declaring:
I will make those who are of the synagogue of Satan, who claim to be Jews though they are not, but are liars—I will make them come and fall down at your feet and acknowledge that I have loved you. - Rev. 3: 9
Not only will the WT fall, but the Lord will make them fall down at the feet of those whose trust is in Christ alone. There, in that position will they be made to understand the utter rejection of the Lord and the love he has for many of those they called Babylonish whores.
The last will be first in the kingdom of God.
Will they be forced to view from afar the marriage supper of the Lamb? I personally believe so.
You prepare a table before me in the presence of my enemies. - Ps. 23:5
This is what victory looks like for XJW believers.
"Vengeance is mine saith the Lord" and it will hurt in ways that no physical pain can compare to.
