We look forward to seeing our loved ones again because of the Bible's promise at Acts 24:15 "And I have hope toward God, which hope these men also look forward to, that there is going to be a resurrection of both the righteous and the unrighteous." One day soon the earth will be a paradise again, which was Jehovah God's original purpose for the earth according to Isaiah 65:20-22. The day will come when even long-lived trees will seem to us as transient as the grass, coming and going while we continue living forever!
