That the sinful passions were aroused by the law means that
since the law reveals God’s will, we immediately reject it; or
humans use the law of God to advance their own sinful agenda.
When Paul says that the law arouses sinful passions, he means that the law instigates the underlying sinful nature. The sinful nature is naturally rebellious toward God, so when humans encounter the will of God in the law, it arouses the sinful nature to reject it. We can detect that this is Paul’s meaning because he explains as much in Romans 7:7–11. There he writes that when the law says not to covet, sin seizes the opportunity so that the law produces all kinds of covetousness. In other words, the law awakens the sinful nature, instigating sin.
Some contend that when Paul writes that the law arouses sin, he means that the sinful nature uses the law to enact sinful tendencies. For example, the Jews used the law to condemn Jesus to death. Further, because of the law they excluded the Gentiles from the people of God. In other words, when Paul says the law aroused sin, he means that sinful humans use the law to enact their sinful desires.
The problem with this view is that the immediate context suggests not that the Jews use the law to enact their sinful passions, but that the law arouses their sinful passions. For Paul writes in Romans 7:7 that he would not have known what it is to covet if the law did not say, You shall not covet.
In other words, it’s not that humans use the law to enact the sinful nature, but that the law arouses the sinful nature. In other words, the law instigates what lies dormant, that is, humanity’s inherent sinfulness.
So when Paul writes that the law arouses sinful passions, he means that humanity’s inherent sinfulness is aroused by the law.
Interpretation 1:
Since the law reveals God’s will, we immediately reject it.
Summary:
Paul is explaining something profound about human nature. Humans have a sinful nature that is inherently rebellious toward God. Since the law is from God, as soon as we hear it, since we naturally reject anything that originates from God, we do the opposite of the law. Thus, the law arouses sin in that it instigates our inherent ungodly rebellion.
We cannot escape our sinful nature by our own effort, because our sinful nature prevents us from following God’s will. It is important to recognize our fallen state so that we will embrace the grace of God in Jesus Christ, and allow the Holy Spirit to transform us into people with godly desires.

Minor differences:
Our authors seem to agree that Paul has in mind that since the law is from God, it instigates our natural rebellion against God, arousing us to sin.
Douglas Moo articulates this view concisely when he writes, The law, in setting forth God’s standard, arouses sin by stimulating human beings’ innate rebelliousness against God.
1 In other words, humans naturally want to rebel against God and since the law is from God, we naturally want to disobey it.
John MacArthur explains how the law arouses sin similarly. He writes, The Law, in declaring what is wrong, also arouses evil in the unregenerate person because his naturally rebellious nature makes him want to do the very things he learns are forbidden.

Interpretation 2:
Humans use the law of God to advance their own sinful agenda.
Summary:
Humans are inherently sinful, and the law of God arouses sin in that humans sometimes use the laws of God to advance their sinful goals. For example, the Jews used the tenets of the law to exclude the Gentiles, and the Jewish leaders used it to crucify Jesus.
Advocates:
James Dunn
Frank Thielman
Minor differences:
Our authors agree that when Paul says the law arouses sin, he has in mind that sinful people use the law to advance their sinful agendas.
James Dunn draws out this point by explaining that the Jews misunderstood the purpose of the law, and by so doing, used the law to initiate sin. For example, the law boosted their self-righteousness, leading them to exclude the Gentiles.7
Frank Thielman offers other examples to drive home this interpretation. For example, he says that the Jewish leaders leaned on the teachings of the law to commit the ultimate sin, which was the crucifixion of Jesus. Likewise, Paul utilized the tenets of the law to persecute the church.8 In these circumstances the law arouses sin, even though the law itself is good.

5 For while we were living in the flesh, our sinful passions, aroused by the law, were at work in our members to bear fruit for death.
