Paul emphasizes that true confidence for Christians comes not from the flesh but from faith in Jesus Christ.
In Philippians 3:3, Paul illustrates that Christians are the 'circumcision, which worship God in the Spirit and rejoice in Christ Jesus, and have no confidence in the flesh.' This assertion distinguishes the believer's reliance on Christ rather than personal achievements or adherence to the law. The flesh, characterized by its weakness and sinfulness, cannot produce the spiritual confidence required for salvation. The believer's confidence arises from being united with Christ and recognizing all glory belongs to Him. Furthermore, this understanding compels believers to declare, as Paul did, that if God had not chosen them first, they would have no ability or desire to choose Him. This underscores the fundamental Reformed doctrine of election, which is the source of our assurance and proper disposition toward God.
