I've been where you are, not wishing this life to end! Wanting the Lord to wait for His return for His children.
But to realize that while we will not be held back by the physical body and it's ailments, we will still have a life, a purpose, and we will know each other, recognize those family and friends who also trusted in God.
To know that animals will be back in their originally created state: eating off the land and none being prey, "the lion will lay down with the lamb" peace... that's just exciting!
