For what if some did not believe? shall their unbelief make the faith of God without effect?
God forbid: yea, let God be true, but every man a liar; as it is written, That thou mightest be justified in thy sayings, and mightest overcome when thou art judged.
But if our unrighteousness commend the righteousness of God, what shall we say? Is God unrighteous who taketh vengeance? (I speak as a man)
God forbid: for then how shall God judge the world?
For if the truth of God hath more abounded through my lie unto his glory; why yet am I also judged as a sinner?
And not rather, (as we be slanderously reported, and as some affirm that we say,) Let us do evil, that good may come? whose damnation is just.
What then? are we better than they? No, in no wise: for we have before proved both Jews and Gentiles, that they are all under sin;
As it is written, There is none righteous, no, not one:
There is none that understandeth, there is none that seeketh after God.
They are all gone out of the way, they are together become unprofitable; there is none that doeth good, no, not one.
Their throat is an open sepulchre; with their tongues they have used deceit; the poison of asps is under their lips:
Whose mouth is full of cursing and bitterness:
Their feet are swift to shed blood:
Destruction and misery are in their ways:
And the way of peace have they not known:
There is no fear of God before their eyes.
Now we know that what things soever the law saith, it saith to them who are under the law: that every mouth may be stopped, and all the world may become guilty before God.
Therefore by the deeds of the law there shall no flesh be justified in his sight: for by the law is the knowledge of sin.
But now the righteousness of God without the law is manifested, being witnessed by the law and the prophets;
Even the righteousness of God which is by faith of Jesus Christ unto all and upon all them that believe: for there is no difference:
For all have sinned, and come short of the glory of God…
(From: Romans 3:3-23 KJV)
