2 Timothy 2:19-21

19Nevertheless, God’s solid foundation stands firm, sealed with this inscription: “The Lord knows those who are his,” and, “Everyone who confesses the name of the Lord must turn away from wickedness.” 20In a large house there are articles not only of gold and silver, but also of wood and clay; some are for special purposes and some for common use. 21Those who cleanse themselves from the latter will be instruments for special purposes, made holy, useful to the Master and prepared to do any good work.
