Why is Christ living in us important for Christians?

The concept of Christ living in us is central to the Christian faith, highlighting a profound spiritual union with the Savior. In Galatians 2:20, Paul writes, 'I am crucified with Christ: nevertheless I live; yet not I, but Christ liveth in me.' This verse illustrates the transformation that occurs when a believer is united with Christ, resulting in a new nature that seeks to honor God. Paul also indicates that this new life is sustained by faith in the Son of God, reflecting how our identity and actions should flow from this relationship with Christ. The presence of Christ in believers is not only a source of strength and guidance but also the essence of our hope and assurance of eternal life.
