What are the true marks of a Christian?

In Philippians 3:3, the Apostle Paul gives three defining evidences of a life transformed by grace:
• Worship by the Spirit of God
• Glory in Christ Jesus
• Put no confidence in the flesh

Christianity is not about what you add to Christ. It is about what God has done to you. Like a surgeon who cuts in order to heal, God performs sovereign surgery on the human heart—removing what is dead and diseased and leaving behind unmistakable “scars of grace.”

Has God cut to your heart?
Has He removed your confidence in yourself?
Has He left the marks of true conversion on your life?

This sermon explores the biblical meaning of “we are the circumcision,” tracing the promise of heart transformation from Deuteronomy 30:6 and Romans 2:28–29 to its fulfillment in Christ. We’ll see how true worship (John 4:23–24), spiritual discernment (1 Corinthians 2:12–14), and boasting in Christ alone define the people of God.

Three marks. One Savior. No confidence in the flesh.
