1 Peter 3:3–4: Beauty in the Hidden Heart
Peter does not forbid outward care; he relocates beauty to the hidden person of the heart. A gentle and quiet spirit is called incorruptible because it outlasts hair, gold and clothing, and God himself calls it precious.
1 Peter 3:3–4: What a Christian Man Should Wear
1 Peter 3:3–4 gives no clothing list for men. It tells wives that beauty should not be only outward, but the hidden character of the heart, and that redirects every reader from what is worn to who is wearing it.
