What does the Bible say about the priesthood of believers?

The concept of the priesthood of believers is articulated in 1 Peter 2:9, where believers are identified as a 'royal priesthood.' This designation highlights that, unlike the Old Testament where only the Levites could serve as priests, all believers in Christ are given the privilege to approach God directly. This is made possible through the redemptive work of Jesus, our great high priest, who has opened the way for us to commune with God without the need for an earthly mediator. Believers are called to serve and worship, bringing forth sacrifices of praise and living out their faith in virtue as an expression of their royal heritage in Christ.
