In Strong’s Concordance, the word peacemaker means “pacificator” which is some that pacifies. Simply to bring or restore a state of peace per dictionary.com. This means there is conflict that must be restored, but how is it restored?
You can only restore peace through strength, not only mental strength, but physical strength. Teddy Roosevelt had it stated perfectly: “Speak softly, but carry a big stick.”
Ronald Reagan showed this through action by creating a large military, which was rarely used. This resulted in the final downfall of Socialist Communism.
Now we are living in a time where the pacifist are practicing the opposite. They are shrinking the military and keep telling people they are not going to use it. As a result the military is more busy than ever and underpowered.
It is like saying not to spank a child, which results in the child rebelling, spoiled as in the saying spare the rod, and spoil the child. (BTW, NEVER USE A REED OR A BRANCH THAT IS JUST WRONG).
Jesus stated that the peacemakers are blessed. Does that mean that chaos makers are cursed?
I would say yes.
