16 - yet we know that no one is justified by the works of the law but by the faithfulness of Jesus Christ. And we have come to believe in Christ Jesus, so that we may be justified by the faithfulness of Christ and not by the works of the law, because by the works of the law no one will be justified.
17 - But if while seeking to be justified in Christ we ourselves have also been found to be sinners, is Christ then one who encourages sin? Absolutely not!
18 - But if I build up again those things I once destroyed, I demonstrate that I am one who breaks God's law.
19 - For through the law I died to the law so that I may live to God.
Vs. 16 - “Yet we know” - For all the advantages he had as a Jew, Paul understood these ultimately did him go good. (See: Phil. 3:4-7) It may have been easier for him to understand that God was the ultimate judge and savior. It may have been easier for him to see Christ as the Son of God, and the Messiah. Yet - knowing this background information got Paul no closer to a personal relationship with God than the sorriest Gentile. Paul received salvation through faith in Jesus Christ.
“Justified” - Repeated three times in this verse alone. This word has a legal sense in that God declares the believer to be righteous and acceptable because Christ took our sins upon Himself on the cross. We are now declared righteous. (See: 1 Cor. 1:30; Rom. 3:24, 25; 2 Cor. 5:21; Rom. 4:6-8.) From many years ago, there was a mnemonic for “justified” - “Just as if I had never sinned.”
This is not a purely New Testament (or New Covenant) concept, In the O.T., God is shown as pleading the case of the sinner and executing the justice for the sinner. The accusers are put to shame, for the sinner has seen the light and lives! (See: Mic. 7:9-10) The judgement against the sinner has been executed. The sentence does not fall on the sinner, but on God Himself.
“Works of the law” - Useless! Paul develops this theme in greater detail in Romans. He also proclaims this in Philippians 3:4-7.
“By the faithfulness of Jesus Christ” - Stop and look at that phrase. It is not by our faithfulness. It is Christ who was faithful to the will of the Father. (See: Phil. 2:5-11) Paul knew well of the works required by the Law. He also knew the end result of following the Law added up to nothing, eternally speaking. (See: Titus 3:5,6). The pairing of these two phrases: “works of the law” and “faithfulness of Jesus Christ” emphasizes the uselessness of rigidly following the law, because it is only by Christ’s obedience that we are declared righteous.
“no one will be justified” - If you are not JUSTIFIED you are NOT SAVED. If you rely on your ability to be perfect, to pay an infinite price to a Holy God, be warned: you have neither the tools nor the skill to pull this off. You are doomed to failure. Failure in this instance is eternal separation from God. This sounds harsh. It is, but it is reality.
If you are doing a job, and an expert, or your boss, tells you that what you are doing will fail - do you ignore that statement and continue on with what you are doing? Why would you do that?
Vs. 17 - “while seeking to be justified…” “found to be sinners” - Do you suppose that after you have accepted Christ as Savior you will ever sin again? There are a some denominations that hold the doctrine of ‘sinless perfection’. I am not sure how that particular belief system deals with Rom. 7:15-24, or 1 John 1:8-9. On this side of heaven, we will commit sins. Our old nature is ‘Dead Man Walking’, but not absent until we are resurrected. Jesus understands you and I as we live our lives, must deal with sin, and surrender to the power and control of the Holy Spirit. Paul is writing to believers who are being told they must follow the Law, even after they have accepted Christ.
Think on this: You acknowledge that Jesus Christ paid for ALL your sin. There is nothing you can do to make yourself holy and acceptable. And yet, you are attempting to keep all of the strictures of the Law in order to make yourself acceptable. Do you imagine that Jesus would say, “Believe in me and you shall be saved. Oh, by the way, if you don't keep the Mosaic Law you have just lost it all, because you are now a sinner having failed to keep the Law.”
“Christ encourages sin” - That’s what is meant by this sentence (or, verse). If Jesus required faith and works for salvation, then He would knowingly lead us from righteousness to sin. We would be going from holiness because of His sacrifice on the cross, to breaking the Law and sin. We know it is not possible to keep the Law. (See the Letter to the Romans.) No wonder answer to the question is “Absolutely not!” Christ died to save us from sin. Christ died to free us from sin, and give us righteousness.
Vs. 18 - “If I build up again... things I once destroyed” - Paul did not destroy the Law. (Christ did not destroy the Law, He fulfilled it - Matt. 5:17). Paul clearly defined that obeying the Law could not justify you with God. Paul’s logical treatment of this possible path to a relationship with God has thus been “destroyed”. That belief has no efficacy. So, why rebuild a path that only leads to failure?
“I demonstrate” - means “I am showing...” I may have said this before, but it is worth repeating: Your behavior, or actions, display what you believe. (See James 2:17-18, 26) You may SAY, “I believe Christ died for my sin.” If you continually have check list of things that must be done in order for God to accept you as His child, your actions show you are not confident that Jesus Paid It All.
“I am the one who breaks God’s law” - God’s law? Not the Law, the one handed to Israel through Moses. He would be breaking the new law: “Believe on the Lord Jesus Christ and you will be saved.” (Matt. 16:31; Rom. 10:9) If you are using some set of rules plus Christ’s death and resurrection, you are showing that you do not believe that Christ is enough.
Vs. 19 - “through the law I died to the law” - The law did not kill Paul. This statement is an allegory. Jesus fulfilled the Law when he died on the cross. Jesus died to pay the cost for all the sins of the world. Believing that Jesus died for this purpose means that Paul is now dead to sin. Jesus took away the penalty of sin, therefore took away death. Not the physical death each of us will face, but the “second death” - eternal separation from God. Faith in Christ equals salvation. Salvation by faith means the Law no longer makes any demands - it has no power. We are “Dead” to the power of the Law.
“So that” - In logical terms: Because this (I died to the Law) happened, the result is that (I live to God) happens.
The message is: there is no way for the second to take place unless the first does. As long as the Law holds sway, the believer is not living by faith, but by works.
“I may live to God” - We are controlled by the law(s) when we order our lives by law(s) - that is the meaning of live to law. Likewise, when we are controlled by the Spirit of God we live to God. Jesus said that to truly worship God we must do it in the spirit. (See: John 4:23, 24)
We are living in the flesh if we try to live by the law. We are trying to live under our own power, which cannot and will not work.
