-Under the old covenant animal blood was shed for the forgiveness of sins
Heb 9:19,20 For when every commandment of the law had been declared by Moses to all the people, he took the BLOOD of calves and goats, with water and scarlet wool and hyssop, and sprinkled both the book itself and all the people, saying, "This is the BLOOD of the COVENANT which God commanded you."
Heb 13:11 For the bodies of those animals whose BLOOD is brought into the sanctuary by the high priest as a sacrifice for SIN are burned outside the camp.
Heb 9:18 Hence even the first covenant was not ratified without BLOOD.
-Without shedding of blood there is no forgiveness of sin.
Heb 9:22 Indeed, under the law almost everything is purified with blood, and WITHOUT the shedding of BLOOD there is NO forgiveness of sins.
-Under the new covenant Jesus’ blood cleanses us from sins and not animals like before
1 John 1:7 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 cleanses us from all sin.
Eph 1:7 In him we have REDEMPTION through his BLOOD, the forgiveness of our trespasses, according to the riches of his grace
-Indeed, the new covenant IS Jesus blood and the forgiveness of sins through his blood
1 Cor 11:25 In the same way also the cup, after supper, saying, "This cup IS the new covenant in my BLOOD. Do this, as often as you drink it, in remembrance of me."
Heb 13:20 Now may the God of peace who brought again from the dead our Lord Jesus, the great shepherd of the sheep, by the BLOOD of the eternal COVENANT,
1 Cor 10:16 The cup of blessing which we bless, is it not a participation in the BLOOD of Christ? The bread which we break, is it not a participation in the body of Christ?
Rom 11:27 "and this will be my COVENANT with them when I take away their SINS."
Heb 10:16-18 "This is the covenant that I will make with them after those days, says the Lord: I will put my laws on their hearts, and write them on their minds," then he adds, "I will remember their SINS and their misdeeds NO MORE." Where there is FORGIVENESS of these, there is no longer any offering for sin.
-Since there is only forgiveness of sin through the blood of Jesus and his blood is the new covenant, and most Jehovah’s Witnesses are not under the new covenant, they have no forgiveness of sin.
-If they are without blood and forgiveness they are also without hope.
