Redefinition and Justification – Overview of Galatians 2:15-21

Galatians 2:15-21

“Well, I’ve been afraid of changing, cause I’ve built my life around you. But time makes you bolder. Even children get older, and I’m getting older too.” –Fleetwood Mac

I can’t imagine what it would be like to lose a loved one. I’m not sure what it is like for a couple to go through a divorce after being married for years. The loss of security that comes when one loses their job after being employed for decades brings no emotional response. But I am sure it is hard. For one to completely change what they once knew, who they once were, and what they used to do because of a cataclysmic event is something I can’t really relate to.

Sure I am a child of divorced parents. Yes, I went to college out of state. And I did move across country for a job opportunity. But I didn’t have a family I was bringing with me. I am relatively new to this thing called “life,” so all these changes didn’t affect me as they would someone who was more accustomed to a certain way of life. I couldn’t imagine how it would impact me having to move across the U.S. if I had a family I would have to take with me. I couldn’t imagine the fear that would come if I would lose my job having to provide for people I love.

This section is the main idea of the whole letter to the Galatians. If someone told me to explain this letter in a couple sentences, I would just point them to Galatians 2:15-21. Here Paul takes a look back at what he went through with calling Peter out on Peter’s hypocrisy. This is probably a summary of what Paul said to Peter, along with some personal testimony, theology (ideas about God), soteriology (understanding salvation), and ecclesiology (understanding what the church is).

Witherington states: “[This] argument is not basically about getting in [to heaven], nor even about how one stays in, but rather about how one goes on in Christ and with the aid of the Holy Spirit.” Here Paul develops his argument stating that to be in Christ does not mean that one follows the Law of Moses but instead the Law of Christ. Paul balances the works of the law with the faithful act of Christ’s crucifixion. This is why he says: “One is not justified by works of the law but by the faithfulness of Jesus Christ” (Gal 2:16b).

Paul is saying that God wants all people to forget who they once were and get a new identity in Christ. “I have been crucified with Christ,” Paul says, “It is no longer I who live, but Christ who lives in me.” Paul is saying that he has to strip his identity as a Jew, and he now has to redefine who he is in Christ. He is encouraging the Galatians to also not become Jewish, get circumcised, and follow the works of the Law. Paul is encouraging them to find their identity instead in Christ.

This would be like someone getting divorced after many years. This would be like someone changing their career right before it was time for them to retire. To be a Christian one had to completely change how they once lived. For many, this would be no easy task. Many grew up being Jewish and following the Law, or they were Gentile and merely did as they pleased. To now go from doing those things to following the Law of Christ would be like completely redefining who they were.

Have you redefined yourself since becoming a Christian? Do you see yourself as your own, or do you see your life as being one in Christ? We need to be unified in Christ! We need to discover who we are as individuals and as a community through the understanding of who Jesus is as the Christ. The gospel is the good news of Christ’s life, death, and resurrection. It is about how Christ has come to set a wicked world to rights. How has the gospel affected your life? Has Christ’s faithful act of dying on a cross transformed your life?

Take time to reflect on who you once were and who you are now that you are in Christ. Take time to remember what Christ has done for you through dying on the cross – the love, the sacrifice, and the implications of that event. Take a moment to remind yourself of your new identity in Christ.
