This episode emphasizes the necessity of God's grace for sanctification and the keeping of God's law. The law is an excellent mirror, revealing the disconnect between ourselves and a holy God. It is nevertheless powerless to transform us and sanctify us, since we are fundamentally sinful apart from God's grace. Paul highlights this fact in Romans 8:3, "what the law could not do, weak as it was through the flesh, God did.." The law reveals our weakness and our desperate need for Christ. It is the "tutor that leads us to Christ." (Gal. 3:24) Christians commonly acknowledge dependence on the grace of God in conversion and infancy in Christ, but trip up later when they revert to relying on their flesh, apart from grace. This was my experience, and I testify how God overthrew my smug self-reliance and gave me a sense of my utter dependence on His power. This gracious power transforms us, helping us keep the law. "I will run the way of your commandments, for you will enlarge my heart." (Psalm 119:32)
Sanctifying Grace: Faith Working through Love
This episode contrasts the inadequacy of the law to perfect the believer with "faith working through love." Paul effectively says that emphasis on circumcision is a moot point: "For in Christ Jesus neither circumcision nor uncircumcision means anything but faith working through love." (Gal. 5:6) Sanctification by appealing to the law is a hopeless endeavor, however sanctification directed by the Spirit leads to the fruit of the Spirit (Gal. 5:22-23) and is aptly described as "faith working through love." This total trust and dependence on God describes walking by the Spirit (Gal. 5:16) and this is the stream by which empowering grace floods the soul. So what would occur if a believer reverts to the law as the means of sanctification? The tributaries of God's grace are damned up by appeal to the works of the law. Faith in God is replaced with fleshly works, which naturally appeal to the works of the law as the ground of justification. God's unmerited favor is set aside, rendered ineffective because it's not invited. "Fallen from grace" and "severed from Christ" both describe believers who presumptuously think they can live the Christian life without empowering grace, that their own power is sufficient. Interestingly, Paul's inclusion of sins of the flesh in Gal. 5:19-21 comes after Paul's indictment of Galatian legalism, almost suggesting that appeal to the law as the means of sanctification actually makes one's condition worse. Paul's focus on sanctification in chapter 5 underscores the conclusion that Paul is principally concerned with Galatian rejection of sanctifying grace, not the justifying grace of salvation.
