1 Peter 3:4 - Wesley's Explanatory Notes

The hidden man of the heart — Complete inward holiness, which implies a meek and quiet spirit. A meek spirit gives no trouble willingly to any: a quiet spirit bears all wrongs without being troubled. In the sight of God — Who looks at the heart. All superfluity of dress contributes more to pride and anger than is generally supposed. The apostle seems to have his eye to this by substituting meekness and quietness in the room of the ornaments he forbids. "I do not regard these things," is often said by those whose hearts are wrapped up in them: but offer to take them away, and you touch the very idol of their soul. Some, indeed only dress elegantly that they may be looked on; that is, they squander away their Lord's talent to gain applause: thus making sin to beget sin, and then plead one in excuse of the other.
