A quick search for quotes on peace pulls up Martin Luther King Jr quite a few times. He was a church leader and activist who was one of the most prominent leaders of the civil rights movement.
His tactic in protest was non-violence. Like this quote says: Peace is not merely a distant goal that we seek, but a means by which we arrive at that goal.
King received the Nobel Peace Prize for combating racial inequality through nonviolent protest in October 1964.
We can be angry, anger is an appropriate response to and gets us moving against injustice, but anger has to be the motivator, and is not the best or safest place to act from. A non-violent response takes a lot of self-control and a deep centered-ness on Jesus.
So we pray.
There is so much injustice all around and we feel it. It makes us mad as it should. When we are angered by it draw us back to center where You are and show us how we might respond from a place of peace in a way that is non-violent because we are Your children and, like we read in the Beatitudes - how wonderful to be a peacemaker. Amen
