We can have what Satan can't, we can live for eternity. This is the reward that is available for you and me. Eternal life is something that we can enjoy. But Satan will be defeated and then destroyed.
When Jesus returns, we will all be young again. I can't say when this will happen, I don't know when. Imagine still being a young man or woman after trillions of years have passed. Unlike today, our youth will never end, it will be something that will last.
There will be no racism, no bullies, everybody will be your best friend. Eternal life is a gift that's available to us but Satan's existence will end. If we love and worship The Lord, we will live forever even though we're currently flawed. Satan will be destroyed but we can have eternal youth because people are loved by God.
