Notice this verse found in Isaiah 25:8- He will swallow up death forever, and the Sovereign Lord Jehovah will wipe away the tears from all faces- What do you think about that? That verse tells us that death will be gone. So not only will people not die, but you'll see your loved one again. That is a promise from God, named Jehovah. But, now, you're sad. And i am so sorry for your loss.
