You will be rewarded for every loss, so why be so anxious? You are people who are going to be eternally rewarded. We deserve no reward. But we are going to be eternally compensated and rewarded for every pain on account of Christ, every loss for his name’s sake. So why should we be so anxious about having our rights being treated properly, and require that people are punished in some overt way when they are unreasonable to us?
A greeting in all cultures is a sign of respect. To blank somebody and to refuse to acknowledge them is counted as an insult. You meet someone in the street, and as soon as you see them you remember the evil they did to you. How can you greet them? It will appear to say that you do not regard the evil they did to you as so great after all, but you do. Nevertheless, in the interests of grace and mercy, you overlook what they have done and greet them anyway; you do not look in another direction and avoid them. If that person is converted to God, which is in his hands not yours, you will be obliged to forgive many wrongs that person may have done you, just as God has forgiven them.
