All this works-based rhetoric only hides the real problem for JW's. They have been told a big fat LIE; and they swallowed it hook, line and sinker. That lie is that the New Covenant is only for those who want to go to heaven as a disembodied spirit. (JW's have no concept of a biblical resurrection where people are reunited with their body soul and spirit, regardless of where they are in God's family. But, that is for another discussion.)
Naturally, if you think you have a choice in the matter, people will predictibly choose bodily existence with all the materials things that you now enjoy as well as those things that you haven't worked hard enough for, or become educated enough to get - here. You think people are going to willingly give up tacos?
The reality is that the New Covenant is "for the forgiveness of sins" and has nothing to do with a limited number of offerings or whether you want to live in your body or as a disembidied spirit.
And taking a cup, he offered thanks and gave it to them, saying: “Drink out of it, all of you, for this means my blood of the covenant, which is to be poured out in behalf of many for forgiveness of sins". Mt. 26: 27-28 NWT
Even if a JW partakes and claims he is in the NC , he is still cursed because he is preaching another message for everyone else. The apostles never taught this nonsense. Gal. 1: 8-9 says that if you preach a different "good news" other than what the apostles preached, you are CURSED.
So, this naturally begs the question: When JW's are destroyed at Armageddon for rejecting the NC "for the forgiveness of sins", will the survivors of Armageddon be able to aquire the houses of JW's for free since they will no longer need them?
