John Wesley on 1 Peter 2:9

But ye - Who believe in Christ Are - In a higher sense than ever the Jews were. A chosen or elect race, a royal priesthood - "Kings and priests unto God," Rev 1:6. As princes, ye have power with God, and victory over sin, the world, and the devil: as priests, ye are consecrated to God, for offering spiritual sacrifices. Ye Christians are as one holy nation, under Christ your King. A purchased people - Who are his peculiar property. That ye may show forth - By your whole behaviour, to all mankind. The virtues - The excellent glory, the mercy, wisdom, and power of him, Christ, who hath called you out of the darkness of ignorance, error, sin, and misery.
