1 Peter 1:7; 1 Peter 1:18; 1 Peter 3:3

7 That the trial of your faith, being much more precious than of gold that perisheth , though it be tried with fire, might be found unto praise and honour and glory at the appearing of Jesus Christ:
18 Forasmuch as ye know that ye were not redeemed with corruptible things, as silver and gold, from your vain conversation received by tradition from your fathers;
3 Whose adorning let it not be that outward adorning of plaiting the hair, and of wearing of gold, or of putting on of apparel;
