Ephesians 4:25, 29, 32

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.

But instead be kind and affectionate toward one another. Has God graciously forgiven you? Then graciously forgive one another in the depths of Christ’s love.
