What does the Bible teach about the necessity of sacrifice for sin?

The biblical narrative underscores the necessity of sacrifice for atonement, as seen in the sacrifices made under the Old Covenant and ultimately in the sacrifice of Christ. Hebrews 9:22 states, 'Without the shedding of blood, there is no forgiveness of sins.' This principle is illustrated throughout Scripture, including David’s need to offer sacrifices after his sinful actions in 2 Samuel 24 to appease God and stop the plague resulting from his sin. David's understanding that personal sacrifice must cost him something is pivotal because it symbolizes the seriousness of sin and the costliness of grace. His act points forward to Christ, who is the ultimate sacrifice, fulfilling the requirement of atonement once and for all, providing a way for sinners to be reconciled to God.
