4:1-6 Apostles were no more than servants of Christ, but they were not to be undervalued. They had a great trust, and for that reason, had an honourable office. Paul had a just concern for his own reputation, but he knew that he who chiefly aimed to please men, would not prove himself a faithful servant of Christ. It is a comfort that men are not to be our final judges. And it is not judging well of ourselves, or justifying ourselves, that will prove us safe and happy. Our own judgment is not to be depended upon as to our faithfulness, any more than our own works for our justification. There is a day coming, that will bring men's secret sins into open day, and discover the secrets of their hearts. Then every slandered believer will be justified, and every faithful servant approved and rewarded. The word of God is the best rule by which to judge as to men. Pride commonly is at the bottom of quarrels. Self-conceit contributes to produce undue esteem of our teachers, as well as of ourselves. We shall not be puffed up for one against another, if we remember that all are instruments, employed by God, and endowed by him with various talents.

4. by myself—Translate, "I am conscious to myself of no (ministerial) unfaithfulness." Bengel explains the Greek compound, "to decide in judgments on one in relation to others," not simply to judge.

am I not hereby justified—Therefore conscience is not an infallible guide. Paul did not consider his so. This verse is directly against the judicial power claimed by the priests of Rome.
