Are You a Peacemaker?

What is a peacemaker? There are false imitations, so what is the Bible's definition? Why is it that only born again believers can be peacemakers? Gandhi, for instance, wasn't a real peacemaker, though he is often thought of as one. Why can't unbelievers be peaceful and be at peace? How are Christians supposed to be of the same mind as Paul commands, if we are not in fact of the same mind? Is one of the two parties in a disagreement supposed to drop his convictions in order to have peace? Which one is supposed to do so? All these questions will be considered and explained in this sermon.
