The document discusses the concept of believers being a royal priesthood based on passages from the Bible. It notes that believers have been made kings and priests by God and are called to offer up spiritual sacrifices as living stones in God's spiritual house. As God's chosen people, believers have priestly privilege in being redeemed and purified by Christ, priestly access to God through the blood of Christ and the Holy Spirit, and a priestly function to show God's praises and declare their fellowship with God and Christ. The overall message is that all believers have the highest honor, calling, and work as priests of God.
