1 Peter 3:4

But let it be the hidden man of the heart . The "hidden" is here equivalent to the "inward man" of Romans 7:22 ; 2 Corinthians 4:16 ; Ephesians 3:16 . It is that life which is "hid with Christ in God" ( Colossians 3:2 ), the life of Christ ("the Second Man") in the heart, fashioning that heart after the likeness of Christ, forming in it "the new man which is renewed in knowledge after the image of him that created him" ( Colossians 3:10 ). This is hidden; it does not display itself like those conspicuous ornaments mentioned in the last verse. In that which is not corruptible , even the ornament of a meek and quiet spirit ; literally, in the incorruptibility of the meek and quiet spirit. This ornament is incorruptible; not like those corruptible things. The meek spirit does not flash into anger, does not answer again, takes harsh words gently and humbly. The quiet spirit is calm and tranquil; peaceful in itself, it spreads peace around. Which is in the sight of God of great price . The adjective πολυτελές is used in Mark 14:3 of the ointment with which Mary anointed our Lord, and in 1 Timothy 2:9 of the " array " which St. Paul discourages for Christian women. Those adornments are costly in the sight of the world; the meek and quiet spirit is precious in the sight of God.
