The front says:
To consider that after the death of the body the spirit perishes is like imagining that a bird in a cage will be destroyed if the cage is broken.
The back says:
Know thou of a truth that the soul, after its separation from the body, will continue to progress until it attaineth the presence of God . . .
It will endure as long as the Kingdom of God, His sovereignty, His dominion and power will endure. It will manifest the signs of God and His attributes, and will reveal His loving kindness and bounty. The movement of My Pen is stilled when it attempteth to befittingly describe the loftiness and glory of so exalted a station.
