How do we know that Jesus' sacrifice was sufficient for sin?

The assurance of the sufficiency of Christ's sacrifice lies in the doctrine of substitution. As articulated in Luke 23, the innocent Jesus was condemned so that the guilty could go free, showing that His sacrifice bore the weight of the sins of His people. Scripture is clear that no other means can satisfy God's justice; only the perfect sacrifice of Christ, who knew no sin, suffices. This love and obedience to God’s will, evidenced in His willingness to suffer, serves as a profound foundation for our faith. The truth that He died and was raised again affirms that His work was complete and accepted by God. Thus, believers can confidently rest in the efficacy of His atoning work.
