How do we know that Jesus' work was complete?

The event of the veil being torn from top to bottom serves as divine confirmation of the completeness of Jesus' atonement for sin. In His final words, "It is finished," Jesus declared that the work required for salvation was accomplished. The tearing of the veil symbolizes that the need for earthly sacrifices, performed by high priests annually, has been fulfilled by Christ, the ultimate sacrifice. This theological truth is further underscored in Hebrews, which explains that Jesus entered the holy place, securing eternal redemption for all who believe.
