Nevertheless, the foundation of God standeth sure, having this seal, the Lord knoweth them that are His. And let every one that nameth the name of Christ depart from iniquity. But in a great house there are not only vessels of gold and of silver, but also of wood and of earth; and some to honour, and some to dishonour. If a man therefore purge himself from these, he shall be a vessel unto honour, sanctified, and meet for the Master's use, and prepared unto every good work. II Timothy 2:19 -21
