Why is the priesthood important for Christians?

The priesthood of all believers underscores the importance of having a personal relationship with God, where each individual can approach God directly without the need for a human mediator. This doctrine reflects the truth that every Christian is called to serve and worship God in every aspect of their lives. As priests under God, believers are tasked with the privilege of offering spiritual sacrifices, such as prayer and acts of service. Moreover, this idea reminds Christians of their responsibility to reflect God's holiness and serve others in love, as priests did in the Old Testament.
