Book 2, CHAPTER 3: The Good, Peaceful Disciple of Christ.
Comment: We must resolve to keep peace when adversity rises against us. Our complaints should only be about our own lack of effort – and should seek always to excuse others and accept blame for ourselves.
We need to maintain peace with God through obedience; with our neighbor by disinterest in his affairs, and with ourselves through self denial.
Chapter 3, In Short.
1. By staying peaceful yourself, you will bring others peace.
2. Bear with others, if you expect others to bear with you.
3. Those who possess the greater peace know how to endure tribulation.
Book 2, Chapter 3, The Good, Peaceful Disciple of Christ
1. First, keep yourself in peace, and then you will be able to bring peace to others. The peaceful disciple does good even more than those who are learned.
Those controlled by their passions turn every good into evil and easily believe evil; whereas one who is good and peaceful converts all things into good.
The disciple who dwells in peace is not suspicious of anyone. But if you are discontent and restless, you are tossed about with many suspicions. You are neither quiet yourself nor do you allow others to be quiet.
You often say what you should not say, and omit what would be easy for you to do. You consider what duties others are bound to perform, and yet neglect those to which you yourself are bound to perform.
Therefore be zealous over yourself first, and then you may righteously be zealous concerning your neighbor.
2. While you will not accept the excuses of others, you are particularly good at excusing and coloring your own actions. If instead you accused yourself and excuse your brother, then justice would be served. If you expect others to bear with you, likewise you need to bear with others.
True charity and humility does not know how to be angry or indignant against anyone except one’s own self. See how far you have to go!
It is a small thing to mingle with the good and the meek (Matt 5:43-48), for this is naturally pleasing to all. Every one of us willingly enjoys peace and likes those who agree with us best. But to be able to live peaceably with the hard and perverse, or with the disorderly, or those who oppose us – is a great grace and highly commended and most courageous.
3. There are who 
keep themselves in peace and keep peace also with others, and there are those who neither have peace nor allow others to have peace. They are troublesome to others, but always more troublesome to themselves. And then there are those who hold themselves in peace, and study to bring others to peace.
Nevertheless, all our peace in this troublesome life lies in humble endurance rather than in avoiding adversities. Whoever knows how to suffer shall possess the greater peace. That disciple is conqueror of himself and lord of the world, the friend of Christ, and the heir of heaven.
