The apostle Peter teaches that Christians are part of a holy, royal priesthood. Our lives should be marked by holiness, compassion, and dignity in the pattern of Christ our Lord. Hypocrisy, indignity, impurity, and gallivanting are all unbecoming of those who profess to be citizens of the Kingdom.
You yourselves like living stones are being built up as a spiritual house, to be a holy priesthood, to offer spiritual sacrifices acceptable to God through Jesus Christ…. But you are a chosen race, a royal priesthood, a holy nation, a people for his own possession, that you may proclaim the excellencies of him who called you out of darkness into his marvelous light. ~ 1 Peter 2:5, 9
