“Some that oppose this doctrine indeed say, that the apostle sometimes means that it is by faith, i. e. a hearty embracing the gospel in its first act only, or without any preceding holy life, that persons are admitted into a justified state; but, say they, it is by a persevering obedience that they are continued in a justified state, and it is by this that they are finally justified. But this is the same thing as to say, that a man on his first embracing the gospel is conditionally justified and pardoned. To pardon sin, is to free the sinner from the punishment of it, or from that eternal misery that is due to it; and therefore if a person is pardoned, or freed from this misery, on his first embracing the gospel, and yet not finally freed, but his actual freedom still depends on some condition yet to be performed, it is inconceivable how he can be pardoned otherwise than conditionally; that is, he is not properly actually pardoned, and freed from punishment, but only he has God’s promise that he shall be pardoned on future conditions. God promises him, that now, if he perseveres in obedience, he shall be finally pardoned, or actually freed from hell; which is to make just nothing at all of the apostle’s great doctrine of justification by faith alone. Such a conditional pardon is no pardon or justification at all, any more than all mankind have, whether they embrace the gospel or no; for they all have a promise of final justification on conditions of future sincere obedience, as much as he that embraces the gospel.”

Context: A means can be justified only by its end. But the end in its turn needs to be justified, From the Marxist point of view, which expresses the historical interests of the proletariat, the end is justified if it leads to increasing the power of man over nature and to the abolition of the power of man over man.

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.

Context: I have no more now to say. I do not know, Hastings, if what I have done is justified or not justified. No — I do not know. I do not believe that a man should take the law into his own hands... But on the other hand, I am the law! As a young man in the Belgian police force I shot down a desperate criminal who sat on a roof and fired at people below. In a state of emergency martial law is proclaimed.
