Hebrew 9:22 Without the shedding of blood, there is no forgiveness of sins
Luke 22:19-20 And He took a cup, and when He had given thanks He said, “Take this, and divide it among yourselves. For I tell you that from now on I will not drink of the fruit of the vine until the kingdom of God comes.” And He took bread, and when He had given thanks, He broke it and gave it to them, saying, “This is my body, which is given for you. Do this in remembrance of me.” And likewise the cup after they had eaten, saying, “This cup that is poured out for you is the new covenant
in my blood.”
John 6:52-56 The Jews then disputed among themselves, saying, “How can this man give us his flesh to eat?” So Jesus said to them, “Truly, truly, I say to you, unless you eat the flesh of the Son of Man and drink his blood, you have no life in you. Whoever feeds on my flesh and drinks my blood has eternal life, and I will raise him up on the last day. For my flesh is true food, and my blood is true drink. Whoever feeds on my flesh and drinks my blood abides in me, and I in him.”
Ephesians 1:7-10 In Him we have redemption through His blood, the forgiveness of our trespasses, according to the riches of His grace, which He lavished upon us, in all wisdom and insight making known to us the mystery of His will, according to His purpose, which He set forth in Christ as a plan for the fullness of time, to unite all things in Him, things in heaven and things on earth.
