How do we know the doctrine of reconciliation through Christ is true?

The doctrine of reconciliation through Christ is grounded in both Old and New Testament Scriptures, showcasing a unified biblical narrative about God’s redemptive plan. Prophecies in Isaiah and other prophets pointed to a Messiah who would not only bear the sins of the people but also establish peace through His death. Isaiah 53 outlines the suffering servant's mission to atone for sin, and this is confirmed in the New Testament where Christ claims this title for Himself.

In Acts 5:31, Christ is exalted as the Prince and Savior, emphasizing His role in granting repentance and forgiveness to His people, which underscores the assurance of reconciliation. The theological implications drawn from these texts affirm that through Christ's sacrificial death, believers are reconnected to God, thus validating the doctrine of reconciliation. The cross serves as the ultimate demonstration of God’s mercy and justice, fulfilling the promises made throughout Scripture and offering a profound basis for faith in Christ as the Prince of Peace.
