How do we know the doctrine of redemption is true?

The truth of redemption lies in the Scriptural testimony regarding Jesus as the Messiah, whose coming was foretold through prophetic writings. Isaiah 53, referenced in the sermon, describes the suffering servant, affirming that He would bear our iniquities. Furthermore, the New Testament confirms this through narratives that depict the intentionality of Christ's actions and the teachings of the apostles who declare His resurrection and the establishment of the new covenant (Acts 2:22-24). This historical and theological convergence demonstrates that God's plan for redemption was realized in Christ, assuring believers of the efficacy of His sacrifice and the security of their salvation. The consistency of Scripture further solidifies the truth of this doctrine, showing God’s faithfulness from Genesis to Revelation.
