How do we know Jesus' sacrifice is true?

The truth of Jesus' sacrifice is substantiated through various channels, including the fulfillment of Old Testament prophecies and the eyewitness accounts of those who were present during his ministry, crucifixion, and resurrection. For instance, Isaiah 53 vividly portrays the suffering servant who bears the iniquities of many, which is fulfilled in Jesus' death. Furthermore, the apostolic testimony found in the New Testament provides a direct account of his sacrificial death and bodily resurrection, affirming his role as the ultimate redeemer. The transformative effect of the Gospel in the lives of believers testifies to its truth, as countless individuals have experienced spiritual regeneration, reconciliation with God, and hope through faith in Christ. This profound change aligns with the promises found in Scriptures, confirming the reality of Jesus' sacrificial atonement.
