Read Matthew 5:9

Peacemakers release tension, they don't intensify it. Peacemakers seek solutions and find no delight in arguments. Peacemakers calm the waters, they don't trouble them. Peacemakers work hard to keep an offense from occurring. And if it has occurred, they strive for resolution. Peacemakers lower their voices rather than raise them. Peacemakers generate more light than heat. 

Blessed are such great-hearted souls!...

Make no mistake, however; peacemaker is not a synonym for appeaser. This is not peace at any price. There are limits.... Smiling at wrongdoing or erroneous teaching doesn't simplify life; it complicates it.

When Christ blessed the peacemakers, He was extolling the value of doing all we can to maintain harmony and support unity. His interest was in making peace where peace is an appropriate objective.
