It isn't just a doctrinal statement being proclaimed. It isn't something they read, but experienced. They experienced a rebirth through this living message. In his great mercy he has given us new birth into a living hope through the resurrection of Jesus Christ from the dead . . . They have been liberated for life.
Liberation carries with the ideal of zest and vitality.
It is a desire locked in our psyches. The angel of God came to salvage their lives from that prison cell. They personally witnessed the powerful message of life. They know the message is vitally relevant to a dying world. The message conveys a person's dignity in the sight of God.
