How can we have true assurance without looking to our works?

Philippians 3:3 emphasizes that we are the true circumcision who worship God in the Spirit and glory in Christ Jesus, having no confidence in the flesh. This means that our assurance of salvation does not derive from our works or merits but solely from faith in Christ's finished work. The assurance of salvation is a work of grace in the believer, granting confidence in our relationship with Christ, independent of our fluctuating performance. This guards us against the pitfalls of self-reliance, thereby ensuring that our hope rests on the solid foundation of Christ.
