Do not grieve the Holy Spirit of God

Let no unwholesome word proceed from your mouth, but only such a word as is good for edification according to the need of the moment, so that it will give grace to those who hear.  Do not grieve the Holy Spirit of God, by whom you were sealed for the day of redemption.  Let all bitterness and wrath and anger and clamour and slander be put away from you, along with all malice.

Ephesians 4:29-31
