The concept of the church as a "kingdom of priests" is significant because it shapes both the church's identity and its purpose. This idea originates from Exodus 19:6, where God promised Israel they would be a "kingdom of priests. This concept, originally applied to Israel, finds its fulfillment in the church Identity: The church, comprised of people from every tribe and nation, is a "holy priesthood", set apart from the rest of the world as a distinct spiritual kingdom under Christ's reign. This identity is rooted in Christ's victory as both King and Priest, offering Himself as the final sacrifice for sin.

As a "kingdom of priests", the church's purpose is to serve and worship God, proclaiming His excellencies and offering spiritual sacrifices through praise, worship, and witness. This priestly service is marked by living sacrificially for others: Following Christ's example, the church is called to demonstrate God's grace and love through acts of mercy and service, pointing others to Christ as the source of reconciliation. Interceding for others: The church's priestly role includes praying for all people, including those in authority, seeking God's mercy and reconciliation in the world. The church's identity as a "kingdom of priests" is a call to holiness and a reminder of the privilege and responsibility to represent Christ to the world. It emphasizes that every member of the church shares in this priestly role, serving as ambassadors of God's grace and reconciliation.
