2 Timothy 2:19-21

Howbeit the firm foundation of God standeth, having this seal, The Lord knoweth them that are his: and, Let every one that nameth the name of the Lord depart from unrighteousness. Now in a great house there are not only vessels of gold and of silver, but also of wood and of earth; and some unto honor, and some unto dishonor. If a man therefore purge himself from these, he shall be a vessel unto honor, sanctified, meet for the master’s use, prepared unto every good work.
