The background to this seems to be the Roman practice of alighting on people and demand transportation, such as Simon who was made to carry the cross. In the ancient world the authorities had the right to commandeer a man to carry baggage for them from one stage to the next.
As believers we absorb an awful lot, especially for the Lord. That is the kind of people we are meant to be: not touchy, not reactive, not like the scribes and the Pharisees. Character is precious. The scribes and the Pharisees were so proud and so touchy and so vindictive that they were incapable of behaviour like this. How quickly in families, petty things become the cause of quarrels. The Pharisees had sub-parties frequently feuding with each other. Christians must be nothing like that. There are Christians who are deeply hurt by things done to them at work because they are Christians; they become seriously unhappy. It is better to absorb such things. We are to show the opposite spirit to the world, for the world counts every wrong done to it, and records each hurt in indelible ink. For some, nothing can be allowed to be forgotten or overlooked. Believers on the other hand are to commit all things to God and leave it to him to judge between wrongs. They are quietly confident of their own integrity without feeling the need to enforce their rights on a fractious world. They do not return evil for evil because they are conscious of the many sins that God in his graciousness has forgiven them, and they live in hope that their enemies will also repent and experience the same forgiveness from a merciful God. The believer is willing to forfeit his rights because he knows that God is able to care for them better than he can care for them himself.
If we are to bear patiently with hurtful things done to us by evil men and women, how much more should we bear patiently with circumstances that providence delivers to us? We stub our toe, we break something we value, we miss a bus. All things come from the hand of God and nothing is an accident. It is for our good and we must accept it humbly without anger or bitterness.
