What does the Bible say about Paul's confession of faith?

In Philippians 3, Paul profoundly expresses that his confidence and self-worth come not from his extensive religious achievements but solely from his relationship with Jesus Christ. He declares that everything he once gained in terms of status and righteousness is now counted as loss for the excellence of knowing Christ. This highlights the core of the Christian faith: our identity and worth are not tied to our accomplishments but rather to our union with Christ, the King of glory. Paul emphasizes that true fulfillment and success come from seeking the Kingdom of God first and knowing Christ more deeply, moving beyond mere doctrinal knowledge into a personal and transformative relationship with the Savior.
