Pegg, one thing I can't seem to learn from the JW website is that when you or other JW's say "death," as you did in your above statement, do you mean physical or spiritual death? I'm assuming you mean physical death.
No one is saved from physical death in this life, nor was such a thing promised by Jehovah. We all die!
To me, salvation means saved from spiritual death, which is separation from God. We can be spiritually dead in this life (as the majority of people are), and sin is what causes that separation. We can be made alive, forgiven, regenerated and saved, by believing Jesus is the Son of God NOW.
In Titus 3, Paul wrote,
3 At one time we too were foolish, disobedient, deceived and enslaved by all kinds of passions and pleasures. We lived in malice and envy, being hated and hating one another.
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.
Even though we have not yet realized the full benefits of salvation yet (eternal life) we are saved in the sense that 1. We have been washed, cleansed of our sins, through the washing of rebirth (born again), and 2. we have been renewed by the Holy Spirit (a new creation).
Through our faith in Christ, we are reconciled back to God by the blood of Jesus. We must continue to work out our salvation. In other words, we can lose it.
Yes, it is in the world to come, that we will never die. Physical death, sickness and all the misery of this world will be no more. This is why we're told not to store our treasures up on this earth, but in heaven, which is pretty much the same as what Paul wrote to Timothy in the verse you cited above.
