Do your best to present yourself to God as one approved, a worker who has no need to be ashamed, rightly handling the word of truth.  But avoid irreverent babble, for it will lead people into more and more ungodliness, and their talk will spread like gangrene.  Among them are Hymenaeus and Philetus who have swerved from the truth, saying that the resurrection has already happened.  They are upsetting the faith of some.  But God's firm foundation stands, bearing this seal: "The Lord knows those who are his," and, "Let everyone who names the name of the Lord depart from iniquity."  Now in a great house there are not only vessels of gold and silver but also of wood and clay, some for honorable use, some for dishonorable.  Therefore, if anyone cleanses himself for honorable use, set apart as holy, useful to the master of the house, ready for every good work.  So flee youthful passions and pursue righteousness, faith, love, and peace, along with those who call on the Lord from a pure heart.  2 Timothy 2:15-22 (ESV)
