Galatians 2:20 (BSB)

I have been crucified with Christ, and I no longer live, but Christ lives in me. The life I live in the body, I live by faith in the Son of God, who loved me and gave Himself up for me.

From Galatians 2. Also in the ESV.

Commentary on Galatians 2:20

• John Calvin (Reformed), Calvin's Commentaries on Galatians 2:20: 20. I am crucified with Christ. This explains the manner in which we, who are dead to the law, live to God. Ingrafted into the death of Christ, we derive from it a secret energy, as the twig does from the root.
• Matthew Henry (Presbyterian), Matthew Henry's Complete Commentary on Galatians 2:11-21: I. From the account which Paul gives of what passed between him and the other apostles at Jerusalem, the Galatians might easily discern both the falseness of what his enemies had insinuated against him and their own folly and weakness in departing from that gospel which he had preached to them.
• John Gill (Reformed Baptist), Exposition of the Old and New Testaments on Galatians 2:20: I am crucified with Christ,.... Not literally, for so only the two thieves were crucified with him, but mystically; Christ was crucified for him in his room and stead, and so he was crucified with him, and in him, as his head and representative.
• Albert Barnes (Presbyterian), Barnes' New Testament Notes on Galatians 2:20: Verse 20. I am crucified with Christ. In the previous verse, Paul had said that he was dead. In this verse he states what he meant by it, and shows that he did not wish to be understood as saying that he was inactive, or that he was literally insensible to the appeals made to him by other beings and objects.
