Ephesians 4:23-25, 29

Now it’s time to be made new by every revelation that’s been given to you. And to be transformed as you embrace the glorious Christ-within as your new life and live in union with him! For God has re-created you all over again in his perfect righteousness, and you now belong to him in the realm of true holiness. So discard every form of dishonesty and lying so that you will be known as one who always speaks the truth, for we all belong to one another.

And never let ugly or hateful words come from your mouth, but instead let your words become beautiful gifts that encourage others; do this by speaking words of grace to help them.
