Heb 10:1-4, 9:12, 10:10-14
In the Old Testament, the priest placed his hands on the head of a ram and made the ram a sin offering to God. (Lev 1:4)
Lev 1:4 And he shall put his hand upon the head of the burnt offering; and it shall be accepted for him to make atonement for him.
In the Old Testament, the annual burnt offerings offered to God cannot make people whole. (Heb 10:1-4)
Heb 10:1 For the law having a shadow of good things to come, and not the very image of the things, can never with those sacrifices which they offered year by year continually make the comers thereunto perfect. 2 For then would they not have ceased to be offered? because that the worshippers once purged should have had no more conscience of sins. 3 But in those sacrifices there is a remembrance again made of sins every year. 4 For it is not possible that the blood of bulls and of goats should take away sins.
Jesus made eternal atonement for us once for all with His own blood. (Hebrews 9:12, Heb 10:10-14)
Hebrews 9:12 Neither by the blood of goats and calves, but by his own blood he entered in once into the holy place, having obtained eternal redemption for us.
Heb 10:10 By the which will we are sanctified through the offering of the body of Jesus Christ once for all. 11 And every priest standeth daily ministering and offering oftentimes the same sacrifices, which can never take away sins: 12 But this man, after he had offered one sacrifice for sins for ever, sat down on the right hand of God; 13 From henceforth expecting till his enemies be made his footstool. 14 For by one offering he hath perfected for ever them that are sanctified.
