What does it mean to be part of a royal priesthood?

In 1 Peter 2:9, believers are referred to as a royal priesthood, signifying their privileged status and role in God's kingdom. This title conveys that every believer is a priest who has unhindered access to God through the blood of Christ, unlike the Old Testament priests who represented the people before God. As a royal priesthood, Christians are called to worship, intercede for others, and proclaim the excellencies of God. This designation also suggests that believers are part of a larger royal family under Christ, the King, which enriches their identity and calls them to live out their faith actively. Being a royal priesthood thus entails both privilege and responsibility in service to God and the community.
