The Lord God Almighty knows that when this eternity has come to its conclusion, the only thing that will matter is whether or not you are a part of the millennial kingdom of God. If you are, then you are guaranteed to see the next eternity, and the next, and the next.
You are guaranteed to see universes unfold, and kingdoms begin their reign. You are guaranteed to see kings take their throne, and queens begin their rule. You are guaranteed life eternal.
