Leviticus 17:11 NKJV
For the life of the flesh is in the blood, and I have given it to you upon the altar to make atonement for your souls; for it is the blood that makes atonement for the soul.’
New Testament
Romans 5:11 KJV ( Peace with God )
And not only so, but we also joy in God through our Lord Jesus Christ, by whom we have now received the atonement.
2 Corinthians 5:18-19 NLT ( We Are God’s Ambassadors ) And all of this is a gift from God, who brought us back to himself through Christ. And God has given us this task of reconciling people to him. 19 For God was in Christ, reconciling the world to himself, no longer counting people’s sins against them. And he gave us this wonderful message of reconciliation.
Colossians 1:15-23 GNT ( The Person and Work of Christ )
Christ is the visible likeness of the invisible God. He is the first-born Son, superior to all created things. 16 For through him God created everything in heaven and on earth, the seen and the unseen things, including spiritual powers, lords, rulers, and authorities. God created the whole universe through him and for him. 17 Christ existed before all things, and in union with him all things have their proper place. 18 He is the head of his body, the church; he is the source of the body’s life. He is the first-born Son, who was raised from death, in order that he alone might have the first place in all things. 19 For it was by God’s own decision that the Son has in himself the full nature of God. 20 Through the Son, then, God decided to bring the whole universe back to himself. God made peace through his Son’s blood on the cross and so brought back to himself all things, both on earth and in heaven. 21 At one time you were far away from God and were his enemies because of the evil things you did and thought. 22 But now, by means of the physical death of his Son, God has made you his friends, in order to bring you, holy, pure, and faultless, into his presence. 23 You must, of course, continue faithful on a firm and sure foundation, and must not allow yourselves to be shaken from the hope you gained when you heard the gospel. It is of this gospel that I, Paul, became a servant—this gospel which has been preached to everybody in the world.
Hebrews 10:11-14 NLT ( Christ’s Sacrifice Once for All ) Under the old covenant, the priest stands and ministers before the altar day after day, offering the same sacrifices again and again, which can never take away sins. 12 But our High Priest offered himself to God as a single sacrifice for sins, good for all time. Then he sat down in the place of honor at God’s right hand. 13 There he waits until his enemies are humbled and made a footstool under his feet. 14 For by that one offering he forever made perfect those who are being made holy.
1 John 2:1-2 NLT ( Christ Our Advocate [ESV] ) My dear children, I am writing this to you so that you will not sin. But if anyone does sin, we have an advocate who pleads our case before the Father. He is Jesus Christ, the one who is truly righteous. 2 He himself is the sacrifice that atones for our sins—and not only our sins but the sins of all the world.
