What evidence confirms a believer's faith?

The evidence of faith in a believer's life is essentially demonstrated through trust in Christ alone for salvation. This faith serves as the evidence of their justification, as articulated in passages like Ephesians 2:8-9. A believer's reliance on Christ signifies their acknowledgment of their total need for grace and their inability to secure salvation through their own merit. The persistent reliance on Christ amidst ongoing struggles with sin further affirms their regenerated state, as true faith will naturally produce a desire to look to Christ for everything, thus becoming the singular evidence of one’s relationship with God.
