How can I be confident in my salvation?

Paul illustrates in his epistle that confidence in salvation should not be based upon personal achievements or religious background, as he mentions his own past as a Pharisee and his zealous adherence to the law. Instead, true confidence must rest in Christ alone, as Paul concludes that all his former accolades are 'counted as loss' for the sake of knowing Christ (Philippians 3:8). The righteousness we possess before God is not earned through law-keeping or good deeds but is bestowed upon us through faith in Christ's atoning work on the cross. Thus, believers can rest in the assurance that their salvation is secure in Jesus, who alone serves as our righteousness (2 Corinthians 5:21).
