Pastor Robert Rohlin again drills in for a deeper look at 1 Peter 2-9. This time he focuses on the phrase -royal priesthood.- Why are Christians called part of a royal priesthood- And what happened in the ordination of a priest in the Old Testament that pertains to us as Christians- The details surrounding the ordination of a priest have a real and present practicality in the lives of every believer.
