The verse highlights that the Law's principle isn't faith, but performance. It starkly contrasts with faith by stating that obedience—doing the commandments—is the path to life according to the Law itself. This shows how fundamentally different the systems of the Law and faith are.
But the law is not of faith, rather “The one who does them shall live by them.”
English Standard Version (ESV)
Paul is contrasting two ways of relating to God: one based on obeying the Law and the other based on faith. He’s already argued in the previous verse that anyone trying to live by the Law is under a curse because they can’t perfectly keep it all. Now, he clarifies that the Law’s promise is conditional on perfect obedience, not on faith.
Paul draws a sharp contrast here. He's not just saying the Law is different from faith; he's saying it operates on entirely opposite principles. What principle does the Law itself announce?
The verse quotes Leviticus 18:5: "The one who does them shall live by them." This isn't a suggestion or a gentle invitation; it's the fundamental operating principle of the Law.
The Law's Contract
The Law presents a clear contract: perform these actions perfectly, and you will live. It requires absolute, unwavering obedience to every single command, in thought, word, and deed.
This isn't about 'trying your best.' The Law demands perfection. If even one tiny part is missed, the whole contract is broken. It's a system of 'do this, and life is yours.'
Faith's Different Path
This stands in stark contrast to faith, which Paul has been discussing. Faith doesn't earn life by doing; it receives life because Christ has already done it all.
Paul sets up a stark 'either/or' situation. If the Law promises life based on 'doing,' how can we possibly receive life from God?
The critical insight here is the fundamental difference in how life is obtained under the Law versus under faith in Christ.
The Law's Promise: A Transaction
The Law operates like a transaction. If you perfectly fulfill its demands ('do them'), then you are promised life ('shall live in them'). It's conditional on your performance. This life is often understood as the continuation of the life Adam had in Eden, or prosperity and blessing in the earthly realm.

Faith's Gift: A New Reality
Faith, on the other hand, doesn't earn life; it receives it. The righteousness that comes through faith is not based on our perfect performance, but on Christ's finished work. We are declared righteous not because we do perfectly, but because we believe in the One who did perfectly and died for our failures.
This gift of life through faith is far greater – it’s eternal life, a restored relationship with God.
Paul contrasts the Law's demand for perfect, personal obedience for life with the reality that no one can meet that standard, pointing instead to faith in Christ for life.
