“Speak and act as those who are going to be judged by the law that gives freedom, because judgment without mercy will be shown to anyone who has not been merciful. Mercy triumphs over judgment.” (James 2:12-13, NIV)
The disciple of Jesus should endeavor to be merciful in all of his or her judgments because the measure by which we judge others shall be used to judge us; and the mercy we extend to others shall be returned to us.
This does not mean that we should ever excuse evil, or turn a blind eye to wrongdoers. Yet, even the harshest judgments — rightfully made — can be tempered with mercy if sympathy is shown, and if the doorway to reconciliation is left open.
The disciple of Jesus speaks and acts as one whose words and deeds shall be called to account in both this world, and in the world to come. – Luther
