Romans 3:8

and why not (as we are slanderously reported, and as some affirm that we say), Let us do evil, that good may come? whose condemnation is just. [But some of you Jews, objecting to my argument, will say, "According to your statements, the unbelief and disobedience of us Jews, with reference to God's Scripture, drew out, displayed and magnified the faithfulness and goodness of God in fulfilling his Scripture. Therefore, since our unbelief, etc., added to the glory of God by commending his righteousness, is not God unjust to punish us for that unbelief, etc., since it works such praiseworthy results? "My answer is, God forbid that sin should become righteousness, for if sin ceases to be sinful, how shall God judge the world, since then there shall be no sin to be condemned or punished? You see, then, the absurdity of your question, since it is a practical denial of the divinely established fact that there is to be a day of judgment. Sin, though it may, by its contrast, display the righteousness of God, is nevertheless utterly without merit. As an illustration, my case is analogous to yours. You arraign me before the bar of Jewish opinion, even as you yourselves are arraigned before the bar of God; yet you would not permit me to use before you the very same argument which you are seeking to use before God. You Jews regard me as a sinner, and charge me with being untrue to the Jewish religion, and with being a false representative of it, in that I declare it to be fulfilled in the gospel. Now, my lie (as you consider it), in this respect, redounds to the glory of God by being a contrast to his truthfulness. But would you Jews acquit me of the sin of heresy if I should make use of this your argument? And, again, if your reasoning is correct, why should I not, as certain, meaning to slander me, report that I do, and affirm that I say, Let us do evil that good may come? But those who avow such principles are justly condemned. Thus Paul showed that, in condemning him (though falsely), they condemn the very argument which they were seeking to affirm in Romans 3:5]
