SB, explain please how the rejection of the blood of the New Covenant as forced by wt on "the other sheep" (not taking the emblems) is related to the ongoing -or already ended- "times of the nations" . thanks.
Sure, no problem.
The bible divides human history into dispensations or time periods. The OT prophets could not see the age of grace that we have been living in since Pentecost. So, they wrote about the time period they were living in as well as the future Millennium reign. The Age of Grace was hidden from them - "great is this mystery of godliness". During this age a person could be considered godly (righteous and thus worthy of admission into God's family) by nothing more than child-like faith in the Resurrection of Jesus. There are many other fantastic promises made to this church-age group as well.
Jesus spoke to both groups. The groups are separated by time periods, nothing more.
By contrast, the Millennium age will be populated by the surviving nations after Jesus defeats the anti-christ and saves what is left of earth's population. This group has different promises made to them. Scriptures directed at them show that, they are not glorified, are not immortal, they sin and die during the Millennium. Obviously, church age believers have a very different experience according to the scriptures and the WT exploits people's ignorance of the end times. 2/3 of evangelicals hold the views I am describing in this post.
Scripture tells us to "rightly divide" the word of God. This of course implies that there will be those who will wrongly divide the word of God. Jesus warned:
For then shall be great tribulation...And except those days should be shortened, there should no flesh be saved: but for the elect's sake those days shall be shortened. Then if any man shall say unto you... Behold, he is in the is in the secret chambers [invisible]; believe it not, For there shall arise false Christs...Behold, I have told you before[hand].
He is coming with the clouds, and every eye will see Him - Rev. 1:7
So, theoretically if the the WT changes their view on the Gentile Times (Age of Law) ending around 1914 this would mean that the promises made effectual during the age of grace would still be available to "whosoever", including the average JW. The WT believes we have been in the Millennium age since 1914.
The entire purpose of the WT is to shut down the age of grace and thus deny salvation to millions, not to mention to create as many broken families and chaos as possible for those affected by WT policies along the way. If they can cause significant psychological/emotional damage for those who do leave, trusting won't even be possible for some.
"hypocrites! For you shut up the kingdom of heaven against men; for you neither go in yourselves, nor do you allow those who are entering to go in" - Jesus
