Speak in truth and love about your neighbor

As far as your former way of life is concerned, you were taught to take off the old self, which is corrupted by its deceitful desires, and to be renewed continually in the spirit of your mind, and to put on the new self, which has been created to be like God in righteousness and true holiness.
Therefore, after you put away lying, let each of you speak truthfully with your neighbor, because we are all members of one body. “Be angry, yet do not sin.” Do not let the sun go down while you are still angry. Do not give the Devil an opportunity.
 ...Do not let any unwholesome talk come from your mouths. Say only what is beneficial when there is a need to build up others, so that it will be a blessing to those who hear. Do not grieve the Holy Spirit of God, with whom you were sealed for the day of redemption. Get rid of every kind of bitterness, rage, anger, quarreling, and slander, along with every kind of malice. Instead, be kind and compassionate to one another, forgiving one another, just as God in Christ has forgiven you.
