"Blessed are the peacemakers, for they will be called Children of God."
As peacemakers, we are called to walk a difficult line. By no means does being a peacemaker mean we are to avoid all conflict, but it also requires us to have a certain level of humility to turn away from unnecessary fights. Thus, as peacemakers, we are called to put our wants and opinions aside in pursuit of the greater good, recognizing that our way is not always the right way.
Jesus provides us with examples of peacemakers as he re-taught the Jewish tradition. In Matthew's fifth chapter, we are warned that should not only love our neighbors, but also our enemies. We are not better than anyone if we are only loving to those who are kind to us. The peacemakers will not only make their homes and means available to those they know, but to those that they do not.
Peacemakers go beyond those physical actions; they are the even-tempered who are not bent on seeking their own way. Something we could all probably work on from time to time. It can be difficult to resist an argument, particularly when we know we are right, but then we are no better than the scribes and Pharisees of Jesus' time. They, too, knew that they were right. But sometimes, it is important to act with love than with righteousness.
Take a moment to consider Matthew's chapter 6, verses 5-8 and consider the humility with which that person prays. Are your arguments made with a similar hope and humility? Or are they made to show yourself off, announcing your knowledge and prowess?
