What does the Bible say about Christ living in us?

Galatians 2:20 states, 'I am crucified with Christ: nevertheless I live; yet not I, but Christ liveth in me.' This profound truth of Christ living in us indicates that through faith, believers are united with Christ in His death and resurrection. It reflects a deep spiritual intimacy, where Jesus is not only an external Savior but also the very source of life within His followers. The believer's identity is transformed, as they share in Christ's righteousness and power to live a new life dedicated to Him.
