It's taken a long time, but we are assured that the wait will be so worth it.
Yes, it will. The Resurrection
alone will make it worth the wait.
Another related issue to consider is that, while bad things have happened since the rebellion in Eden,
individuals have only had to endure 70, or 80, or 90 years. Less than that, if they were ill or mistreated. Then they've died.
When the Kingdom comes and these ones are resurrected, i.e., brought
back to life, their previous 80-year hardship will be forgotten! Reminds us of Isaiah 65:17, doesn't it?
Since we know that Jehovah cares for humans (especially His servants, Isaiah 63:9), I think that's how Jehovah must look at the barbarous things that happen to people: on an
individual basis.
When you consider the Holocaust -- 10 million innocent people systematically slaughtered -- it's almost too much to fathom! But if you look at it on an individual basis....yes, it's still very sad, yet a person could only individually bear what he himself could,
then that was it! Afterwards, they "RIP",
until Jesus begins the Resurrection (John 5:28-29), and they're given life again and reunited with their loved ones! That'll be a marvelous time....when all past relationships -- between brothers and sisters, loving parents and children, dear friends -- will be restored, everyone (who wants it) living forever! -- Revelation 21:3-4.
What more good things will come, we'll just have to wait and see! -- 1 Corinthians 2:9; Isaiah 11:6-9 will be awesome, too.
