Then there is a fourth truth-the truth that all true believers are priests. In I Peter 2:5-9, we learn that we are holy priests and royal priests.
As holy priests we offer up spiritual sacrifices to God by Jesus Christ (v. 5). These sacrifices include:
As royal priests we show forth the excellencies of Him Who has called us out of darkness into His marvelous light (I Peter 2:9). This means that every believer is expected to witness for Christ, both by life and by the spoken word.
As holy priests we go into the sanctuary to worship. As royal priests we go out- into the world to testify.
The idea that worship and service are the functions of a special group known as priests or clergymen is foreign to the New Testament. All believers are priests and should be free to exercise their priestly functions.
