Galatians 2:17

But if, while we sought to be justified in Christ, we ourselves also were found sinners, is Christ a minister of sin? God forbid. [But if we were forced by Christ's light to confess that we were sinners under the law, so that we turned our backs upon the law as a means of justification; and if we were now so disappointed and dissatisfied with the justification which we have obtained from Christ, that we in turn abandon him and seek to return to the law, what will be said of Christ? Will not all be compelled to say that, so far as we are concerned, he has proved himself not a minister to our justification, but rather a minister to our sense of sin? And is he indeed such a minister? God forbid the thought! We may regard Paul's reproof as closing here and look upon the rest of the chapter as an elaboration of the thought addressed to the Galatians. But his address to them begins properly at Galatians 3:1; so we prefer to take it as a continuation of the reproof, wherein Paul drops the plural for the singular that he may declare to Peter his own intentions in the matter.]
