And another thing.....yes, some people have gone through terrible situations. Jehovah God is aware of all we suffer.
You can say “6,000 years of pain is awful!”
But really, for each individual, it’s only been 70-90 years. If someone really went through hard times (say cancer), it’s far less. Only a couple years.
Then, when their life is over I.e., they die, they “RIP” until the Resurrection, promised by our Lord, Jesus, @ John 5:28-29, John 6:44.
When the dead are resurrected back to life on Earth, it will be under the Kingdom rule (Matthew 6:9-10), which will bring blessings like that foretold @ Revelation 21:3-4.
including that at Isaiah 11:6-9, and Isaiah 33:24. (They will be “pardoned for their error.”)
The issue of sovereignty will have been settled, and Jehovah & His Son Jesus will apply the benefits of Jesus’ ransom sacrifice ....sin will be no more. Imperfection and death will be “no more”!
