This episode rehashes all the influences of the Holy Spirit indicative of the circumcision of Christ. Unregenerate man is dominated by the flesh and incapable of distinguishing flesh from spirit. This state changes when he is born again and circumcised by Christ, making the believer better at distinguishing flesh from spirit. But this ability is compounded exponentially when the Word of God is consumed by the Christian. With respect to repentance from dead works, the Word of God exposes us to ourselves so that we can discern what is fleshly and respond in repentance.
Repent of everything, especially the old self
This episode highlights the necessity of repenting from dead works in its fullest sense: we repent of transgressions AND we abandon hope in the flesh itself, specifically its ability to live the Christian life. If we don't embrace this holistic approach to repentance, we likely fall into the Galatian error, which is living the Christian life in the power of the flesh. Based on this all-encompassing repentance, we make progress in sanctification by identifying with the circumcision of Christ (the cutting away of the flesh) and the death of the old self on the cross, based on Romans 6:7. Holistic repentance from dead works makes sanctification possible.
