Let no evil talk come out of your mouths, but only such as is good for edifying, as fits the occasion, that it may impart grace to those who hear. And do not grieve the Holy Spirit of God, in whom you were sealed for the day of redemption. Let all bitterness and wrath and anger and clamor and slander be put away from you, with all malice, and be kind to one another, tenderhearted, forgiving one another, as God in Christ forgave you.
– Ephesians 4:29-32
