"Do your best to present yourself to God as one approved by him, a worker who has no need to be ashamed, rightly explaining the word of truth. Avoid profane chatter, for it will lead people into more and more impiety, and their talk will spread like gangrene.
"In a large house there are utensils not only of gold and silver but also of wood and clay, some for special use, some for ordinary. All who cleanse themselves of the things I have mentioned will become special utensils, dedicated and useful to the owner of the house, ready for every good work. Shun youthful passions and pursue righteousness, faith, love, and peace, along with those who call on the Lord from a pure heart."
--2 Timothy 2:15-16, 20-22
