2 Timothy 2:19-21

But the sure foundation of God standeth firm, having this seal: the Lord knoweth who are his; and let every one depart from iniquity who nameth the name of the Lord.

But in a great house there are not only vessels of gold and of silver, but also of wood and of earth: and some indeed unto honour, but some unto dishonour.

If any man therefore shall cleanse himself from these, he shall be a vessel unto honour, sanctified and profitable to the Lord, prepared unto every good work.
