The circumcision of Christ initiated at conversion makes possible repentance from dead works and the repentance from the old self. This episode highlights the various Scriptural signs that indicate the circumcision of Christ, and these henceforth enable the believer to repent in the ongoing process of sanctification. The believer is first born again by the Word of God (1 Pet 1:23), made a partaker of the divine nature (2 Pet 1:4), and given a new principle from which he "rejoices with the law of God in the inner man" (Rom 7:22). I provide my testimony as a convert coming out of Catholicism where the above 3 signs were evident, even though I hadn't little exposure to Scripture. My conversion led to a hyper-sensitive conscience, which was the Spirit's foundation in me that assisted 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.
