Why is being quickened together with Christ important for Christians?

Being quickened together with Christ, as mentioned in Ephesians 2:5, signifies that believers share in His resurrection and new life. This union is central to the Christian faith, showing that through Christ, believers are not only spiritually revived but also seated in heavenly places with Him (Ephesians 2:6). The reality of this union provides assurance and hope, affirming that believers are no longer dead in trespasses and sins but alive in Christ, which transforms their relationship with God and empowers them to live in obedience and righteousness.
