“The law of faith, being a covenant of free grace, God alone can appoint what shall be necessarily believed by everyone whom He will justify. What is the faith which He will accept and account for righteousness, depends wholly on his good pleasure. For it is of grace, and not of right, that this faith is accepted. And therefore He alone can set the measures of it: and what he has so appointed and declared is alone necessary. No-body can add to these fundamental articles of faith; nor make any other necessary, but what God himself hath made, and declared to be so. And what these are which God requires of those who will enter into, and receive the benefits of the new covenant, has already been shown. An explicit belief of these is absolutely required of all those to whom the gospel of Jesus Christ is preached, and salvation through his name proposed.”

Romans 3:19-31
Epistle to the Romans
Context: 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; Being justified freely by his grace through the redemption that is in Christ Jesus: Whom God hath set forth to be a propitiation through faith in his blood, to declare his righteousness for the remission of sins that are past, through the forbearance of God; To declare, I say, at this time his righteousness: that he might be just, and the justifier of him which believeth in Jesus.
Where is boasting then? It is excluded. By what law? of works? Nay: but by the law of faith. Therefore we conclude that a man is justified by faith without the deeds of the law. Is he the God of the Jews only? is he not also of the Gentiles? Yes, of the Gentiles also: Seeing it is one God, which shall justify the circumcision by faith, and uncircumcision through faith.
Do we then make void the law through faith? God forbid: yea, we establish the law.
