If you love those who love you what credit is that to you? For even sinners love those who love them. And if you do good to those who do good to you what credit is that to you? For even sinners do the same.
Ultimately we have just one moral duty: to reclaim large areas of peace in ourselves more and more peace and to reflect it towards others. And the more peace there is in us the more peace there will be in our troubled world.
