But let every man prove his own work, and then shall he have rejoicing in himself alone, and not in another.
All Commentaries on Galatians 6:4 Go To Galatians 6
John Chrysostom
AD 407
He says this not by way of command but by way of concession. It is as though he had said, “It is absurd to boast, but if you must, do not boast against your neighbor, like the Pharisee.” The person who learns this lesson will also soon give up boasting altogether. Thus Paul’s reason for conceding this was to drive out the larger malady by small steps. For the one who is accustomed to boast with regard to himself alone, and not against others, will soon reform this fault also. If he does not think himself better than others—for that is the meaning of not looking to the other—but is chastened by examining himself by himself, he will later stop this boasting too.
