Romans 3:7

But what if my untruth? It is plain that a charge of untruth was often made against Paul (compare Galatians 1:20; Romans 9:1). No unbelieving Jew questioned the fact that Paul would come into judgment, in spite of the fact that his "faithlessness in becoming a Christian" had made the faithfulness of God to Israel stand out. Paul takes their idea that he is to be judged as a sinner and turns it on them. They believe he lied, but that some good came from it. Yet they condemn him as a sinner. This shows they already understand that even though good may come from sin, the sin is still not excused. [Scholars cannot agree on Romans 3:7-8.]
