1-corinthians 4:4

For I know nothing by myself - Ουδεν γαρ εμαυτῳ συνοιδα· I am not conscious that I am guilty of any evil, or have neglected to fulfill faithfully the duty of a steward of Jesus Christ. The import of the verb συνειδειν is to be conscious of guilt; and conscire has the same meaning: so, in Horace, Nil Conscire sibi, to know nothing to one's self, is the same as nulla pellescere culpa, not to grow pale at being charged with a crime, through a consciousness of guilt.

Yet am I not hereby justified - I do not pretend to say that though I am not conscious of any offense towards God I must therefore be pronounced innocent; no: I leave those things to God; he shall pronounce in my favor, not I myself. By these words the apostle, in a very gentle yet effectual manner, censures those rash and precipitate judgments which the Corinthians were in the habit of pronouncing on both men and things - a conduct than which nothing is more reprehensible and dangerous.

For I know nothing by myself - There is evidently here an ellipsis to be supplied, and it is well supplied by Grotius, Rosenmuller, Calvin, etc. "I am not conscious of evil, or unfaithfulness to myself; that is, in my ministerial life." It is well remarked by Calvin, that Paul does not here refer to the whole of his life, but only to his apostleship. And the sense is, "I am conscious of integrity in this office. My own mind does not condemn me of ambition or unfaithfulness. Others may accuse me, but I am not conscious of that which should condemn me, or render me unworthy of this office." This appeal Paul elsewhere makes to the integrity and faithfulness of his ministry. So his speech before the elders of Ephesus at Miletus; Acts 20:18-19, Acts 20:26-27; compare 2 Corinthians 7:2; 2 Corinthians 12:17. It was the appeal which a holy and faithful man could make to the integrity of his public life, and such as every minister of the gospel ought to be able to make.

Yet am I not hereby justified - I am not justified because I am not conscious of a failure in my duty. I know that God the judge may see imperfections where I see none. I know that I may be deceived; and therefore, I do not pronounce a judgment on myself as if it were infallible and final. It is not by the consciousness of integrity and faithfulness that I expect to be saved; and it does not follow that I claim to be free from all personal blame. I know that partiality to ourselves will often teach us to overlook many faults that others may discern in us.

He that judgeth me is the Lord - By his judgment I am to abide; and by his judgment I am to receive my eternal sentence, and not by my own view of myself. He searcheth the hearts. He may see evil where I see none. I would not, therefore, be self-confident; but would, with humility, refer the whole case to him. Perhaps there is here a gentle and tender reproof of the Corinthians, who were so confident in their own integrity; and a gentle admonition to them to be more cautious, as it was possible that the Lord would detect faults in them where they perceived none.

4:4 I am not conscious to myself of anything evil; yet am I not hereby justified - I depend not on this, as a sufficient justification of myself in God's account. But he that judgeth me is the Lord - By his sentence I am to stand or fall.
