How do we know that the doctrine of Christ bearing sins is true?

The truth that Christ bore our sins is firmly rooted in Scripture, primarily in Isaiah 53, which prophesied about the suffering servant who would take upon Himself the iniquities of many. This doctrine is further confirmed by its fulfillment during the crucifixion, as detailed in Mark 15:28. The continuity of these prophecies and their specific fulfillment in Christ’s life and death reinforce the truth of this vital doctrine. Moreover, as believers reflect on passages like 2 Corinthians 5:21, which asserts that Christ was made sin for us, they find certainty and assurance in the completed work of Christ on the cross.
