Why is the role of priesthood important for Christians?

For Christians, the concept of priesthood is significant because it conveys our access to God through Jesus Christ. In the Old Testament, priests mediated between God and the Israelites, offering sacrifices for their sins. This role is fulfilled in Christ, who not only offers Himself as the ultimate sacrifice but also grants us direct access to God. 1 Peter 2:9 describes believers as a 'royal priesthood', indicating that all Christians have the privilege and responsibility to approach God directly through prayer and worship without the mediation of an earthly priest. This emphasizes the grace of God, as we are invited to come boldly to the throne of grace, knowing we are heard and accepted in Christ.
