What does the Bible say about sacrifice for sin?

The concept of sacrifice for sin is rooted deeply in Scripture, beginning with the Old Testament. In Genesis 22, we see Abraham commanded to offer his son Isaac as a burnt offering, which serves as a foreshadowing of Christ's ultimate sacrifice. This act demonstrates the necessity of a sacrifice to atone for sin; as stated, a sacrifice had to be made to appease God's justice for the sins of His people. Ultimately, Hebrews 9:11-12 clarifies that Christ, as the high priest, entered the holy place with His own blood, obtaining eternal redemption for those He came to save. Therefore, the sacrifices of animals in the Old Testament were mere types and shadows of the perfect Lamb of God, who took away the sin of the world.
