Romans, Isaiah and Justification by Faith Alone


In my quest to discover New Testament midrash (“Second Testament” teachings which are expositions of, or expansions upon, “First Testament” texts), I was perusing Paul’s Use of Isaiah in Romans by Shiu-Lun Shum. Though Shum did not claim as much, I believe we can (and that Paul did) deduce the concept of salvation by faith apart from works from the originating Isaiah passages.

Shum points to Isaiah 32:17 as the foundation for Romans 5:1.

Romans 5:1 reads,

Therefore, since we have been justified by faith, we have peace with God through our Lord Jesus Christ. (ESV)

Isaiah 32:17 reads,

And the effect of righteousness will be peace, and the result of righteousness, quietness and trust forever.

I am beginning with the assumption that Romans 5:1 is indeed a midrash (explanation and expansion) upon Isaiah 32:17. The closer we look at the two passages, the more clear it becomes that they are connected.

A Ransom for Many

Reprinted with permission from Paraklesis, Spring 2007.

Three times, Mark records Jesus’ predictions of His coming passion (Mark 8:31; 9:31; 10:33-34). In His explanation of the third of those prophecies, Jesus tells His followers that He is going to give His life as a ransom (λύτρον): “the Son of Man did not come to be served, but to serve, and to give his life as a ransom for many” (Mark 10:45).

The concept of a ransom doesn’t connect with western culture in the 21st century. The only common use of that word today is in reference to kidnapping—usually by terrorists. But this was a very common word in the first century Greco-Roman world. Although it is used only twice in the New Testament, this word aroused immediate associations in the minds of those who read Mark’s gospel. It comes from the culture of slavery: sacral manumission, the ceremony by which a slave is set free.1 In the case of a polytheistic Greco-Roman,2 the slave owner takes the slave being freed to the temple of his god and sells the slave to the god. He is reimbursed for the slave from the pagan temple treasury.

The ceremony takes place in the presence of witnesses, and the manumission record is often recorded in stone—typically on the temple wall or pillar. This transaction is somewhat of a legal fiction, because it is not really temple money that is involved. Rather the slave himself (or his family or friends) have previously paid the specified amount into the temple treasury. Once the slave owner received the money, the slave became the property of the god. Ownership has been transferred. He does not become a slave of the temple, however, but a protégé of the god. In respect to his former owner, he is now a free man.

Is Salvation a Decision?

John Piper recently told a group of college students that “salvation is not a decision.”

Reactions here at SI were, shall we say, mixed. Some understood Piper to be saying something horrible for the worst of reasons; others took him to be saying something great for the best of reasons, and a few in between suggested that while the statement itself was likely to cause confusion, it is not hard to imagine good reasons for saying it.

In all of the flying feathers, the most important question seemed to get lost: is “salvation” properly characterized as “a decision”? Let’s table the “What did Piper mean?” question and consider the bigger one.

How we answer that question depends on two vital factors: (1) how we define the terms (“salvation” and “decision”) and (2) what we believe about salvation. Sadly, a third factor seems to drive most of the discussion: (3) how much pent up hostility we have toward Reformed or non-Reformed views of the human and divine in the saving of children of wrath (Eph. 2:3). Intense passion against “Calvinism” or “Arminianism,” or “monergism” or “synergism” (quotes intentional, since understandings of these terms vary widely) results in haste to blame one “ism” or the other for every point of disagreement in the doctrine of salvation.

In reality, most who care at all about a question like “Is salvation a decision?” believe nearly all of the same things about “salvation,” but have strong opinions about which features ought to be emphasized and how they ought to be expressed. But because we’re so passionate about them, these relatively small differences lead us to misconstrue what others are saying—and, too often, lead to conflict over what words mean rather than about the substance of our differences.

Depending on how we define the terms, “salvation” both is and is not “a decision.” Since both “salvation” and “decision” are ambiguous terms (they may be defined in more than one way), many combinations of meaning are possible in the statement “salvation is not a decision.”1

Contending with Sin—Redemptively

chainsReprinted with permission from Paraklesis, Summer 2011.

Some years ago, a young wife clinging to her husband hung her head in tears as she shared about her adulterous affair. She had confessed her sin to her husband and to the church some weeks prior. I gently raised her head and shared, “please do not lower your head in shame to anyone in this church—we have all been saved, are being saved, and one day will be saved by the blood of Jesus.” We then began to construct a redemptive solution for this couple.

Scripture portrays a believer’s relationship to sin in a multicolored fashion. We are portrayed as sinners who are completely forgiven and stand completely accepted and loved by God and, at the same time, we are portrayed as saints who continue to struggle with sin. A redemptive paradigm allows this sinning saint identity while avoiding a guilt-driven or grace-distorting double-mindedness.


To engender a redemptive environment, Pastors and counselors should emphasize the threefold sense of salvation: We have been saved (Acts 16:31; 2 Tim. 1:9) from the very penalty, and all penal guilt, of our sin. This past sense or tense of salvation is summed up as justification. Justification entails God pronouncing a judicial verdict and acquittal of all our sins so that each of us stand before Him in Christ’s imputed (not imparted) righteousness and not by our own works (Rom. 3:20-25, Gal. 2:16).

"Whoever believes…that’s it. It’s not whoever turns, tries, seeks, surrenders, stops, starts or anything else!"

Terms That Abuse the Gospel

1. Let Jesus into your heart.
2. Invite Christ into your life.
3. Just say this prayer and you’ll be saved…
4. Make Jesus the Lord of your life (we don’t make him Lord. He IS Lord!)
5. Turn from all your sin (and, no, that’s not what “repent” means!)

Atonement Wars, Part 3

New Testament Support for Penal Substitutionary Atonement

As Our Substitute

We will begin by surveying some of the New Testament references that speak of Christ dying as our substitute. 2 Corinthians 5:21 heads the list: “He made Him who knew no sin to be sin on our behalf, so that we might become the righteousness of God in Him.” Some have termed this “The Great Exchange” as the Sinless One took our sin upon Himself and gave us the righteousness of God. The implication is that this spiritual transaction is made possible only through the sacrifice of Christ. I Peter 2:24 adds detail, “He Himself bore our sins in His body on the cross, so that we might die to sin and live to righteousness; for by His wounds you were healed.” Christ then became sin on our behalf (i.e. in our place) at the Cross, for it is there that He bore our sin in His body. He did so to free us from sin and bring us righteousness, but our healing was made possible only because of His wounds. I Peter 3:18 reiterates the same thought by saying, “For Christ died for sins once for all, the just for the unjust, so that He might bring us to God…” In Roman 5:8 Paul writes, “But God demonstrates His own love toward us, in that while we were yet sinners, Christ died for us.” Christ death was “for us.” His death accomplished what nothing else could. Jesus Himself speaks of penal substitution when He states that He came “to give His life a ransom for many” (Mark 10:45). And John the Baptist declared Jesus “the Lamb of God who takes away the sin of the world” (John 1:29).
