What does the Bible say about Christ dwelling in our hearts?

In Ephesians 3:17, Paul prays that Christ may dwell in the hearts of believers by faith. This signifies a deep, spiritual relationship where Christ takes residence in the believer's heart, a work that is fundamentally the ministry of the Holy Spirit. Without the Holy Spirit, it is impossible for Christ to dwell within us. The Holy Spirit reveals the person and work of Christ to us, enabling our faith that allows Christ to indwell our hearts. This communion is not merely positional but is meant to transform our inner beings, affirming that genuine faith is the foundation for Christ's indwelling presence.
