All right, let's talk about this often misunderstood passage.
Romans 4:4-5, a text often used to argue that Paul cannot have meant what he wrote in Romans 2 (and Romans 8 for that matter) about how eternal life is granted according to “how we live”. Here is the relevant material, and I include stuff from the end of Romans 3 for context – remember, it is not Paul who inserts “chapter breaks”:
27Where then is boasting? It is excluded By what kind of law? Of works? No, but by a law of faith. 28For we maintain that a man is justified by faith apart from works of the Law. 29Or is God the God of Jews only? Is He not the God of Gentiles also? Yes, of Gentiles also, 30since indeed God who will justify the circumcised by faith and the uncircumcised through faith (is one. 31Do we then nullify the Law through faith? May it never be! On the contrary, we (establish the Law. 1What then shall we say that Abraham, our forefather according to the flesh, has found? 2For if Abraham was justified by works, he has something to boast about, but not before God. 3For what does the Scripture say? "ABRAHAM BELIEVED GOD, AND IT WAS CREDITED TO HIM AS RIGHTEOUSNESS." 4Now to the one who works, his wage is not credited as a favor, but as what is due. 5But to the one who does not work, but believes in Him who justifies the ungodly, his faith is credited as righteousness, …
A vital point is to note that context clearly shows that the “works” in 4:2 are the works of the Law of Moses. In 3:28, Paul talks about how men are not justified by the works of the Law. It should be clear that this is a reference to the Law of Moses, not to “good works” generally. But even if this were not clear from 3:28, 3:29 seals the deal – Paul is talking about the works of the Law of Moses since the Jew who believes that the works of the Law of Moses justifies could claim that the Gentile, who is not under the Law of Moses, would be excluded from justification. And Paul clearly wants to argue that the Gentile is also a candidate for justification.
It is not quite as simple as that.
So there is really no doubt – Paul is making an argument about the Law of Moses, not good works in general. So why anybody thinks 4:2 is about “good works” is a mystery to me – Paul does not arbitrarily change topics without notice.
The change is not arbitrary. It is on purpose. Abraham is being used as an example of a man who was justified by faith--the point that he is driving home, both in this chapter and in chapter five. In chapters four and five, the subject is no longer the law; it is justification.
No - in 4:2 Paul says Abraham was not justified by doing the works of the Law of Moses.
Not true at all.
Abraham was not a Jew, but a Gentile. The Law of Moses was not applicable to him. Abraham lived ca.2100 B.C. and Moses lived ca. 1400 B.C. The laws of Moses had no effect on Abraham. Abraham was justified by faith, not the works of general law.
So now we come to the workman. I trust we all understand that this is a metaphor. As such, it cannot be taken literally in all its details – it is a comparison, like all metaphors. Paul has just finished arguing that Abraham, like any other Jew, cannot claim that God “owes” justification to the Jew, and only the Jew, in virtue of the cultural marker of the Law of Moses.
1. God does not owe any man anything.
2. Abraham is not/was not a Jew. He came from Ur of the Chaldees. He was justified by faith when he believed God.
The issue to this point is not “does someone who does good works have a claim on God”, it is “does the Jew – the one who is under the Law of Moses – have a claim on God”.
No one does. Not the Jew; not the Gentile; and not Abraham.
Romans 4:2 For if Abraham were justified by works, he hath whereof to glory; but not before God.
--Abraham did not have any claim on God whatsoever.
The workman expects to be paid because he has done something. Fine. What is the parallel to Abraham? The parallel is that Abraham might think he has claim on justification because of his obedience to the Law of Moses, not because he has done “good works”. Paul is no doubt spinning in his grave, wondering how people have ignored the flow of the argument and instead impose their own “Paul must be denying justification by good works” scheme onto his text.
Abraham was not justified by works as verse 2 emphasizes:
Romans 4:2 For if Abraham were justified by works, he hath whereof to glory; but not before God.
--He could only glory or boast about his works before man, not before God.
Romans 4:3 For what saith the scripture? Abraham believed God, and it was counted unto him for righteousness.
--His justification came by faith and faith alone. That is how a man is justified, and has always been justified. There is no other way. It is by faith alone. This is further emphasized in chapter five:
Romans 5:1 Therefore being justified by faith, we have peace with God through our Lord Jesus Christ:
Romans 4:4 Now to him that worketh is the reward not reckoned of grace, but of debt.
--The workman receives his wage or salary because he earns it. It is not a gift, a reward, something given out of grace. It is given as a debt owed, for he earned it.
Romans 4:5 But to him that worketh not, but believeth on him that justifieth the ungodly, his faith is counted for righteousness.
--To the one who never did a good work in his life, but simply believed on Christ, that man is justified. Why? Because it is only Christ that can justify the sinner, and he does it by faith and faith alone, as Paul teaches in Rom.5:1.
