Paul brings further clarity and correction to the false teachers in Ephesus, who had wrongly taught the purpose of the law and our relationship with it. Paul reveals that rather than make us perfect, the law reveals our imperfection, and reveals God as the only righteous one. It is only through Jesus that the law empowers us for healthy, right living rather than bondage. Paul uses his own life as an example of how Jesus is able to save even the “chief of sinners,” while the law would always be unable to do so.
We know that the law is good if one uses it properly. We also know that the law is made not for the righteous but for lawbreakers and rebels, the ungodly and sinful, the unholy and irreligious, for those who kill their fathers or mothers, for murderers, for the sexually immoral, for those practicing homosexuality, for slave traders and liars and perjurers—and for whatever else is contrary to the sound doctrine that conforms to the gospel concerning the glory of the blessed God, which he entrusted to me.
I thank Christ Jesus our Lord, who has given me strength, that he considered me trustworthy, appointing me to his service. Even though I was once a blasphemer and a persecutor and a violent man, I was shown mercy because I acted in ignorance and unbelief. The grace of our Lord was poured out on me abundantly, along with the faith and love that are in Christ Jesus.
Here is a trustworthy saying that deserves full acceptance: Christ Jesus came into the world to save sinners—of whom I am the worst. But for that very reason I was shown mercy so that in me, the worst of sinners, Christ Jesus might display his immense patience as an example for those who would believe in him and receive eternal life.
