So Stephen are you saying ALL (Every single one) is denied salvation?
Well, I agree with Boyzone's advise in some respects we can't judge others, we can only surmise
Mind you, let us bear in mind that Paul exhorts us to have good judgement on this earth, as the saints will judge angels 1 Corinthians 6
Also, to surmise suggests a lack of evidence. However, I would say there is a wealth of evidence against the WT doctrines, and unfortunately those who follow them.
You cannot discern the individual based on religious affliation..... besides if anything you might have picked up on from JWN is that while there are many JWs who follow men in regards to shuning, there are many who are just as likely to not personally believe or even understand the whole teachings of the WTS.
All that is important is knowing Jesus.
Matthew 7:19-23 (New International Version)
19 Every tree that does not bear good fruit is cut down and thrown into the fire. 20 Thus, by their fruit you will recognize them.
21 "Not everyone who says to me, 'Lord, Lord,' will enter the kingdom of heaven, but only he who does the will of my Father who is in heaven. 22 Many will say to me on that day, 'Lord, Lord, did we not prophesy in your name, and in your name drive out demons and perform many miracles?' 23 Then I will tell them plainly, 'I never knew you. Away from me, you evildoers!'
Is the WT actually bearing "good fruit"? Galatians 5:22-23
Are they actually following the will of the Father? John 5:22-24 John 6:40 John 14:23-24 John 12:26
Or are they something not planted by the Father?
Matthew 15:13-14 (New International Version)
13 He replied, "Every plant that my heavenly Father has not planted will be pulled up by the roots. 14 Leave them; they are blind guides. If a blind man leads a blind man, both will fall into a pit."
Also, note below, the importance Paul places on "according to the scriptures". Even then, there were people preaching a different gospel Galatians 1
1 Corinthians 15 (New International Version)
The Resurrection of Christ
1 Now, brothers, I want to remind you of the gospel I preached to you, which you received and on which you have taken your stand. 2 By this gospel you are saved, if you hold firmly to the word I preached to you. Otherwise, you have believed in vain.
3 For what I received I passed on to you as of first importance: that Christ died for our sins according to the Scriptures, 4 that he was buried, that he was raised on the third day according to the Scriptures, 5 and that he appeared to Peter, and then to the Twelve.
Paul makes it clear, those who believe a different gospel "believed in vain".
Romans 5:8-11 (New International Version)
8 But God demonstrates his own love for us in this: While we were still sinners, Christ died for us.
9 Since we have now been justified by his blood, how much more shall we be saved from God's wrath through him! 10 For if, when we were God's enemies, we were reconciled to him through the death of his Son, how much more, having been reconciled, shall we be saved through his life! 11 Not only is this so, but we also rejoice in God through our Lord Jesus Christ, through whom we have now received reconciliation.
How can JWs be saved if they reject the blood of Jesus which saves?
Anyhow, bear these verses in mind
Titus 3:4-7 (New International Version)
4 But when the kindness and love of God our Savior appeared, 5 he saved us, not because of righteous things we had done, but because of his mercy. He saved us through the washing of rebirth and renewal by the Holy Spirit, 6 whom he poured out on us generously through Jesus Christ our Savior, 7 so that, having been justified by his grace, we might become heirs having the hope of eternal life.
1 Peter 4:17-18 (New International Version)
17 For it is time for judgment to begin with the family of God; and if it begins with us, what will the outcome be for those who do not obey the gospel of God? 18 And,
"If it is hard for the righteous to be saved,
what will become of the ungodly and the sinner?"
This whole chapter is good on the subject. Note what Paul says concerning the Israelites Romans 10
All the best,
