1 PETER 3:4
rather let it be the hidden person of the heart, with the incorruptible beauty of a gentle and quiet spirit, which is very precious in the sight of God.
In context this verse is directed to the women of the church that apostle Peter is addressing (see vss. 1-6). Yet I think it’s just as applicable for the bride of Christ, which of course includes all of His saintly disciples.
We are as saints “…the royal daughter…” (PSA 45:13) of our Abba Father.
This verse speaks of “the incorruptible beauty…” that the LORD instills in all of us over time as we walk with Him, yield to His will, embrace the holiness of Christ:
ECCLESIASTES 3:11
He has made everything beautiful in its time. Also He has put eternity in their hearts, except that no one can find out the work that God does from beginning to end.
