Charles Spurgeon Commentary 1 Peter 3:3-4

"Whose [adorning] let it not be the outward adorning of braiding the hair, and of wearing jewels of gold, or of putting on apparel; but [let it be] the hidden man of the heart, in the incorruptible [apparel] of a meek and quiet spirit, which is in the sight of God of great price." — 1 Peter 3:3-4 (ASV)

There is no ornament like that. No taste can ever conceive anything so lovely as a holy character. No expensive materials, and no ingenious fashioning of them, can ever produce such true beauty as a meek and quiet spirit.

You must have known some godly matrons, venerable Christian women, whose gentle piety has blessed the whole household of which they formed a part. They attained supreme authority over all simply by yielding; they gained a queenly position in the house by gentleness and quietness. Nobody dared to offend them — not because they would have been angry, but because they were themselves so inoffensive, so kind, so gentle.
