…in this human world there is no greater blessing than liberty. You do not know. I, who for forty years have been a prisoner, do know. I do know the value and blessing of liberty. For you have been and are now living in freedom, and you have no fear of anybody. Is there a greater blessing than this? Freedom! Liberty! Security! These are the great bestowals of God. Therefore, praise ye God!
