What does the Bible say about the remission of sin?

Hebrews 9:22 states, '...and almost all things are by the law purged with blood. And without shedding of blood is no remission.' This emphasizes that throughout Scripture, the necessity of bloodshed for forgiveness is a prominent theme. From the sacrifices in the Old Testament to the ultimate sacrifice of Christ, blood has always been the means of atonement that allows for the remission of sin. The premise rests not just in the deeds of man but fundamentally in God's covenant with humanity, where Christ's sacrificial death satisfies divine justice.
