II. Note the higher court of conscience.
Our Apostle is not to be taken here as contradicting what he says in other places. ’I judge not mine own self,’—yet in one of these same letters to the Corinthians he says, ’If we judged ourselves we should not be judged.’ So that he does not mean here that he is entirely without any estimate of his own character or actions. That he did in some sense judge himself is evident from the next clause, because he goes on to say, ‘I know nothing against myself.’ If he acquitted himself, he must previously have been judging himself. But his acquittal of himself is not to be understood as if it covered the whole ground of his life and character, but it is to be confined to the subject in hand—viz. his faithfulness as a steward of the mysteries of God. But though there is nothing in that region of his life which he can charge against himself as unfaithfulness, he goes on to say, ‘Yet am I not hereby justified?’
Our absolution by conscience is not infallible. I suppose that conscience is more reliable when it condemns than when it acquits. It is never safe for a man to neglect it when it says, ‘You are wrong!’ It is just as unsafe for a man to accept it, without further investigation, when it says, ‘You are right!’ For the only thing that is infallible about what we call conscience is its sentence, ’It is right to do right.’ But when it proceeds to say ’This, that, and the other thing is right; and therefore it is right for you to do it,’ there may be errors in the judgment, as everybody’s own experience tells them. The inward judge needs to be stimulated, to be enlightened, to be corrected often. I suppose that the growth of Christian character is very largely the discovery that things that we thought innocent are not, for us, so innocent as we thought them.
