What the Bible says about redemption and atonement

Hebrews 9:11-15

But Christ having come as a high priest of the coming good things, through the greater and more perfect tabernacle, not made with hands, that is to say, not of this creation, nor yet through the blood of goats and calves, but through his own blood, entered in once for all into the Holy Place, having obtained eternal redemption. For if the blood of goats and bulls, and the ashes of a heifer sprinkling those who have been defiled, sanctify to the cleanness of the flesh: how much more will the blood of Christ, who through the eternal Spirit offered himself without defect to God, cleanse your conscience from dead works to serve the living God? For this reason he is the mediator of a new covenant, since a death has occurred for the redemption of the transgressions that were under the first covenant, that those who have been called may receive the promise of the eternal inheritance.

Leviticus 16:15-16

Then he shall kill the goat of the sin offering, that is for the people, and bring his blood within the veil, and do with his blood as he did with the blood of the bull, and sprinkle it on the mercy seat, and before the mercy seat. He shall make atonement for the Holy Place, because of the uncleanness of the children of Israel, and because of their transgressions, even all their sins; and so he shall do for the Tent of Meeting, that dwells with them in the middle of their uncleanness.

Isaiah 53:4-6

Surely he has borne our sickness, and carried our suffering; yet we considered him plagued, struck by God, and afflicted. But he was pierced for our transgressions. He was crushed for our iniquities. The punishment that brought our peace was on him; and by his wounds we are healed. All we like sheep have gone astray. Everyone has turned to his own way; and Yahweh has laid on him the iniquity of us all.

John 1:29

The next day, he saw Jesus coming to him, and said, “Behold, the Lamb of God, who takes away the sin of the world!

2 Corinthians 5:17-21

Therefore if anyone is in Christ, he is a new creation. The old things have passed away. Behold, all things have become new. But all things are of God, who reconciled us to himself through Jesus Christ, and gave to us the ministry of reconciliation; namely, that God was in Christ reconciling the world to himself, not reckoning to them their trespasses, and having committed to us the word of reconciliation. We are therefore ambassadors on behalf of Christ, as though God were entreating by us: we beg you on behalf of Christ, be reconciled to God. For him who knew no sin he made to be sin on our behalf; so that in him we might become the righteousness of God.

Exodus 12:1-14

Yahweh spoke to Moses and Aaron in the land of Egypt, saying, This month shall be to you the beginning of months. It shall be the first month of the year to you. Speak to all the congregation of Israel, saying, ‘On the tenth day of this month, they shall take to them every man a lamb, according to their fathers’ houses, a lamb for a household; and if the household is too little for a lamb, then he and his neighbor next to his house shall take one according to the number of the souls; according to what everyone can eat you shall make your count for the lamb. Your lamb shall be without defect, a male a year old. You shall take it from the sheep, or from the goats: and you shall keep it until the fourteenth day of the same month; and the whole assembly of the congregation of Israel shall kill it at evening. They shall take some of the blood, and put it on the two door posts and on the lintel, on the houses in which they shall eat it. They shall eat the meat in that night, roasted with fire, and unleavened bread. They shall eat it with bitter herbs. Don’t eat it raw, nor boiled at all with water, but roasted with fire; with its head, its legs and its inner parts. You shall let nothing of it remain until the morning; but that which remains of it until the morning you shall burn with fire. This is how you shall eat it: with your belt on your waist, your shoes on your feet, and your staff in your hand; and you shall eat it in haste: it is Yahweh’s Passover. For I will go through the land of Egypt in that night, and will strike all the firstborn in the land of Egypt, both man and animal. Against all the gods of Egypt I will execute judgments: I am Yahweh. The blood shall be to you for a token on the houses where you are: and when I see the blood, I will pass over you, and there shall no plague be on you to destroy you, when I strike the land of Egypt. This day shall be to you for a memorial, and you shall keep it a feast to Yahweh: throughout your generations you shall keep it a feast by an ordinance forever.

Colossians 1:13-14

who delivered us out of the power of darkness, and translated us into the Kingdom of the Son of his love; in whom we have our redemption, the forgiveness of our sins;

Hebrews 10:10

by which will we have been sanctified through the offering of the body of Jesus Christ once for all.

Romans 5:8-11

But God commends his own love toward us, in that while we were yet sinners, Christ died for us. Much more then, being now justified by his blood, we will be saved from God’s wrath through him. For if, while we were enemies, we were reconciled to God through the death of his Son, much more, being reconciled, we will be saved by his life. Not only so, but we also rejoice in God through our Lord Jesus Christ, through whom we have now received the reconciliation.

Titus 2:13-14

looking for the blessed hope and appearing of the glory of our great God and Savior, Jesus Christ; who gave himself for us, that he might redeem us from all iniquity, and purify for himself a people for his own possession, zealous for good works.
