How do we know believers are united with Christ?

Scripture affirms that believers have a profound union with Christ that transcends mere positional status. This relationship is depicted in the analogy of the vine and branches, illustrating that Christians are not just connected to Christ but are integral parts of His body, sharing in His life and blessedness. Romans 8:17 elucidates that believers are heirs with Christ, which underscores the intimacy and richness of this union. Through this relationship, believers are not only loved and accepted by the Father but are also called to reflect Christ's glory to the world. Therefore, one's assurance and identity as a child of God are deeply rooted in this vital union.
