Christ redeemed us by offering his own blood as a sacrifice.

Hebrews 9:11-14

11 But when Christ came as our Supreme Priest, he brought the good things that are now available. When he appeared, he went into God’s presence in heaven. That is like a [MET] very great and perfect tent not made by humans {which no human made} [SYN]; that is, it is not part of the world God created. It was better than the tent Moses set up here on earth. 12 When a Supreme Priest goes into the inner room in the tent each year, he takes goats’ blood and calves’ blood to offer as a sacrifice. But Christ did not do that. It was as though he went into that very holy place only once, taking his own blood with him. By doing that, he eternally redeemed us. 13 The priests sprinkle on people goats’ blood and bulls’ blood and the water that has been filtered through the ashes of a red heifer that has been completely burned. By performing that ritual, they can ritually cleanse the bodies of those who are ceremonially unclean. Furthermore, performing those rituals enabled people to have fellowship with God again. 14 So, because we know what Christ accomplished when his blood flowed when he died for us [PRS, MTY], we will be very certain that we are not guilty of having done those things that those who are spiritually dead do. As a result, we can serve God, who is all-powerful. The priests always offer to God animals with no defects. Similarly, when Christ offered himself as a sacrifice to God, he was sinless [MET]. He did that as a result of God’s eternal Spirit helping him.
