Honor all. Two words, a command and the object of the command (1 Pet 2:17). God’s word through Peter is an imperative (τιμήσατε) to all Christians: HONOR. The object of the command (πάντας) is sweeping: ALL.
In the context, ruling authorities and human institutions are in mind. However, the “all” broadens it out to include human beings without exception. All human beings of different ages, genders, ethnicities and talents are image bearers infused with great dignity.
Honor is naturally due an image bearer of the Creator, here that honor is reinforced with a command. People should walk away feeling many things after having engaged a follower of Christ, not least among these is honor. Christian, honor all.
