What does it mean to be a chosen generation and royal priesthood?

In 1 Peter 2:9, believers are referred to as a 'chosen generation, a royal priesthood, a holy nation.' This designation underscores the transformative effect of the Gospel, indicating that all Christians are members of a new covenant community equipped for worship and ministry. As a royal priesthood, we have the privilege to approach God directly in prayer and offer spiritual sacrifices, which are accepted through Christ. This identity also calls us to bear witness to God's grace and glory in the world, thus fulfilling our role as ambassadors of His kingdom. The dignity of being chosen by God elevates our purpose and mission in life as we represent Him in every sphere.
