Ephesians 1:7

1 John 1:7-9 NIV
But if we walk in the light, as he is in the light, we have fellowship with one another, and the blood of Jesus, his Son, purifies us from all sin. If we claim to be without sin, we deceive ourselves and the truth is not in us. If we confess our sins, he is faithful and just and will forgive us our sins and purify us from all unrighteousness.

1 Peter 1:18-19 NIV
For you know that it was not with perishable things such as silver or gold that you were redeemed from the empty way of life handed down to you from your ancestors, but with the precious blood of Christ, a lamb without blemish or defect.

1 Peter 2:24 NIV
“He himself bore our sins” in his body on the cross, so that we might die to sins and live for righteousness; “by his wounds you have been healed.”

Colossians 1:14 NIV
in whom we have redemption, the forgiveness of sins.

Hebrews 9:12-15 NIV
He did not enter by means of the blood of goats and calves; but he entered the Most Holy Place once for all by his own blood, thus obtaining eternal redemption. The blood of goats and bulls and the ashes of a heifer sprinkled on those who are ceremonially unclean sanctify them so that they are outwardly clean. How much more, then, will the blood of Christ, who through the eternal Spirit offered himself unblemished to God, cleanse our consciences from acts that lead to death, so that we may serve the living God! For this reason Christ is the mediator of a new covenant, that those who are called may receive the promised eternal inheritance —now that he has died as a ransom to set them free from the sins committed under the first covenant.

Hebrews 9:22 NIV
In fact, the law requires that nearly everything be cleansed with blood, and without the shedding of blood there is no forgiveness.

Matthew 26:28 NIV
This is my blood of the covenant, which is poured out for many for the forgiveness of sins.

Philippians 4:19 NIV
And my God will meet all your needs according to the riches of his glory in Christ Jesus.

Romans 3:24 NIV
and all are justified freely by his grace through the redemption that came by Christ Jesus.
