What does the Bible say about living by the power of Christ?

The Apostle Paul in Philippians 4:13 declares, 'I can do all things through Christ which strengtheneth me,' underscoring the necessity of relying on Christ's power for spiritual endurance and life. This concept is further echoed in Galatians 2:20, where Paul states, 'I am crucified with Christ: nevertheless I live; yet not I, but Christ liveth in me.' This indicates that our spiritual vitality and ability to face life's challenges come not from our own strength, but from Christ living and working within us.
