Hebrews 9:22

And according to the Law, one may almost say, all things are cleansed with blood, and without shedding of blood there is no forgiveness.

Ephesians 1:7

In Him we have redemption through His blood, the forgiveness of our trespasses, according to the riches of His grace,

1 John 1:7-9

but if we walk in the light as He Himself is in the light, we have fellowship with one another, and the blood of Jesus His Son cleanses us from all sin. If we say that we have no sin, we are deceiving ourselves, and the truth is not in us. If we confess our sins, He is faithful and righteous to forgive us our sins and to cleanse us from all unrighteousness.
