For the ministry of reconciliation to be fulfilled, it was necessary for whom to be in Christ?

The ministry of reconciliation refers to God's work through Christ to restore the broken relationship between humanity and Himself due to sin. For this reconciliation to be fulfilled, it is essential that God is in Christ. This concept is rooted in the understanding that Jesus embodies God's desire to reconcile the world to Himself.

In 2 Corinthians 5:19, it specifically states that "God was in Christ, reconciling the world unto Himself." This highlights that it was God's initiative to join with humanity through Christ, enabling the possibility of redemption and reconciliation. Thus, the presence and action of God within Christ are pivotal for the ministry of reconciliation to be established and realized.

Other options, while important in the context of the broader Christian faith, do not reflect this fundamental aspect of reconciliation. Disciples, Christians, and angels serve various roles in God's plan, but it is the divine presence of God in Christ that is crucial for the fulfillment of this particular ministry.
