Why is the doctrine of union with Christ important for Christians?

The doctrine of union with Christ is foundational to understanding the Christian life. Through this union, believers identify with Christ in His death, burial, and resurrection. This relationship not only defines their identity as children of God but also grants them access to all the benefits of Christ's redemptive work, including forgiveness, righteousness, and eternal life. Furthermore, this union allows Christians to participate in His victory over sin and death, ensuring that they stand securely in the grace of God and are empowered to live in accordance with His will. This doctrine is a source of great joy and comfort, emphasizing that believers are never alone but are continually supported and transformed by Christ.
