1 Corinthians 3:16-18

Do you not know and understand that you [the church] are the temple of God, and that the Spirit of God dwells [permanently] in you [collectively and individually]? If anyone destroys the temple of God [corrupting it with false doctrine], God will destroy the destroyer; for the temple of God is holy (sacred), and that is what you are. Let no one deceive himself. If anyone among you thinks that he is wise in this age, let him become a fool [discarding his worldly pretensions and acknowledging his lack of wisdom], so that he may become [truly] wise. [Is 5:21]
