Peter continues his message to the persecuted pilgrims as he demonstrates that their calling is to fulfil a huge purpose in the plan of God. These very same persecuted people, who were once not a people, are living stones, being built into a living spiritual house, a royal priesthood and a holy nation whose purpose is to proclaim the praises of Him, who called them out of darkness into His marvellous life. This is the pilgrims' purpose across all ages.
