"It's no great thing to be able to talk with those that are good and meek, for this is naturally pleasing to all. And all of us would willingly have peace and love for those that best agree with us. 
But to live peacefully with those that are harsh and perverse, or disorderly, or such as oppose us, now that is a great grace, and highly commendable and manly. Some there are that keep themselves in peace and also have peace with others. But there are some that are neither at peace within themselves, nor allow others to be in peace; they are troublesome to others, but always more troublesome to themselves." Thomas A. Kempis.
