How do we know Christ's sacrifice is enough for our salvation?

The certainty of Christ’s sacrifice being sufficient for salvation rests on its completeness and perfection. Scripture reveals that Christ's work was finished upon His death and resurrection, satisfying the requirements of God's righteousness. Since His sacrifice was perfect and fully executed, there is no need for further offerings or rituals. This is highlighted by the truth that Christ is not only our altar but also our high priest, interceding on our behalf. Thus, believers can have confidence in the efficacy of His atonement as recorded in Scripture, reinforcing that nothing can be added to the redemptive work of Christ. The belief in His completed work is essential for assurance of salvation.
