2 Corinthians 5:18–21 explains God’s work of reconciliation through Jesus Christ. It teaches that God, through Christ, restored our relationship with Himself and entrusted believers with the message of reconciliation. Though Christ was without sin, He took on our sin so that we might receive God’s righteousness in Him. This passage declares redemption, forgiveness, and the call for believers to serve as ambassadors for Christ, inviting the world to be made right with God.
