The Bible teaches that Jesus' sacrifice was the perfect and final atonement for sin, declared complete when He exclaimed, 'It is finished.'
The Bible affirms that Jesus' sacrifice was unique and definitive. In John 19:30, Jesus declares, 'It is finished,' signifying that His work, which was to bear the wrath of God for humanity's sins, was complete. Unlike the ongoing sacrifices of the Old Testament, which served merely as types and shadows, Christ's offering was perfect, as He was the unblemished Lamb of God. His death fulfilled the ceremonial law and established a new covenant in which believers no longer need to offer animal sacrifices, as Christ's sacrifice suffices for all sin.
