James 2: 12-13 ” Speak and act as those who are going to be judged by the Law that gives freedom, because judgement without mercy will be shown to anyone who has not been merciful. Mercy triumphs over judgement.”

From the Beatitudes we learn that, “Blessed are the merciful, for they will be shown mercy.” (Matthew 5:7)  Take that thought along with the Scripture here in James and we can understand a little better that our faith is empty when we are unmerciful.  For if you think about it…we must show mercy in the same way as God has shown mercy to us.
