You also, as living stones, are built up as a spiritual house, to be a holy priesthood, to offer up spiritual sacrifices, acceptable to God through Jesus Christ.
an holy priesthood: The house of God is composed of priests. Individually we are all priests. Under the Old Testament, the spiritual temple was the nation itself with one special group chosen to officiate; under the New Testament all Christians constitute a "priesthood" wherein every worshiper has access to God through Christ (Hebrews 9:11-28). Together, not separately, we constitute a priesthood.
