How do we know Christ's death accomplished our salvation?

The significance of Christ's death is rooted in the fulfillment of Old Testament prophecy and the complete bearing of our sins. Mark 15:25 articulates the moment of crucifixion as pivotal, indicating that this was the culmination of God's redemptive plan. Scholars note the mocking of Christ as King as a fulfillment of prophecies from Psalms and Genesis, which underscored that His suffering and death were necessary for our redemption. The crown of thorns symbolizes the curse of sin He took upon Himself, while His rejection of the wine mingled with myrrh demonstrates His commitment to endure suffering fully, without dulling the pain, for our sake (Isaiah 53:4-5). Thus, the entirety of Christ’s sufferings serves as the basis for the assurance of our salvation.
