The Old Covenant was about written laws, blood sacrifices and priests.
The New Covenant is not about written laws, blood sacrifices and priests.
What is then the New Covenant all about?
Doesn't God said through Jeremiah that it is about the heart? Do we have to speculate about it?
So, the type of worship Peter is referring to in 1 Peter 2:1-5: is that of the new covenant. If you believe it is about the Old Covenant, please share with us your rationale.
The New Covenant is all about Jesus blood. There are plenty of passages declaring that is true.
Facts- There are 86 verses in the New Testament that mentions the word “blood.” There are 25 verses in the New Testament that mention Jesus's blood
Matthew 26:26-29
While they were eating, Jesus took bread, and when he had given thanks, he broke it and gave it to his disciples, saying, “Take and eat; this is my body.”27 Then he took a cup, and when he had given thanks, he gave it to them, saying, “Drink from it, all of you. 28
This is my blood of the covenant, which is poured out for many for the forgiveness of sins.29 I tell you, I will not drink from this fruit of the vine from now on until that day when I drink it new with you in my Father’s kingdom.”
Hebrews 9:22
Because all things are purged by blood in The Written Law, and
without the shedding of bloodthere is no forgiveness.
Leviticus 4:20,26,35
And he shall do with the bullock as he did with the bullock for
a sin offering, so shall he do with this: and the priest shall make an
atonement for them, and it shall be forgiven them
Leviticus 6:7
And the priest shall make an
atonement for him before the LORD: and it shall be forgiven him for any thing of all that he hath done in trespassing therein.
Leviticus 17:11
For the life of the flesh is in
the blood, and I have given it to you to make
atonement for your souls upon the altar; for it is
the blood that makes atonement for the soul.
A Walk through Hebrews
Hebrews 9
Now the first covenant had regulations for worship and also an earthly sanctuary. 2 A tabernacle was set up. In its first room were the lampstand and the table with its consecrated bread; this was called the Holy Place. 3 Behind the second curtain was a room called the Most Holy Place, 4 which had the golden altar of incense and the gold-covered ark of the covenant. This ark contained the gold jar of manna, Aaron’s staff that had budded, and the stone tablets of the covenant. 5 Above the ark were the cherubim of the Glory, overshadowing the atonement cover. But we cannot discuss these things in detail now.
6 When everything had been arranged like this, the priests entered regularly into the outer room to carry on their ministry. 7 But only the high priest entered the inner room, and that only once a year,
and never without blood, which he offered for himself and for the sins the people had committed in ignorance. 8 The Holy Spirit was showing by this that the way into the Most Holy Place had not yet been disclosed as long as the first tabernacle was still functioning. 9 This is an illustration for the present time, indicating that the gifts and sacrifices being offered were not able to clear the conscience of the worshiper. 10 They are only a matter of food and drink and various ceremonial washings—external regulations applying until the time of the new order.
The Blood of Christ
11 But when Christ came as high priest of the good things that are now already here,[
a] he went through the greater and more perfect tabernacle that is not made with human hands, that is to say, is not a part of this creation. 12 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[
b]
eternal redemption. 13 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. 14 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!
15 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.
16 In the case of a will,[
d] it is necessary to prove the death of the one who made it, 17 because a will is in force only when somebody has died; it never takes effect while the one who made it is living. 18 This is why even the first covenant was not put into
effect without blood. 19 When Moses had proclaimed every command of the law to all the people, he took
the blood of calves, together with water, scarlet wool and branches of hyssop, and sprinkled the scroll and all the people. 20 He said, “
This is the blood of the covenant, which God has commanded you to keep.”[
e] 21 In the same way, he sprinkled with the blood both the tabernacle and everything used in its ceremonies. 22 In fact, the law requires that nearly everything be cleansed with blood, and
without the shedding of blood there is no forgiveness.
23 It was necessary, then, for the copies of the heavenly things to be purified with these sacrifices, but the heavenly things themselves with better sacrifices than these. 24 For Christ did not enter a sanctuary made with human hands that was only a copy of the true one; he entered heaven itself, now to appear for us in God’s presence. 25 Nor did he enter heaven to offer himself again and again, the way the high priest enters the Most Holy Place every year with blood that is not his own. 26 Otherwise Christ would have had to suffer many times since the creation of the world. But he has appeared once for all at the culmination of the ages
to do away with sin by the sacrifice of himself. 27 Just as people are destined to die once, and after that to face judgment, 28
so Christ was sacrificed once to take away the sins of many; and he will appear a second time, not to bear sin, but to bring salvation to those who are waiting for him.
Hebrews 10
The Holy Spirit also testifies to us about this. First he says:
16 “
This is the covenant I will make with them
after that time, says the Lord.
I will put my laws in their hearts,
and I will write them on their minds.”
17 Then he adds:
“
Their sins and lawless acts
I will remember no more.”
18 And where
these have been forgiven, sacrifice for sin is no longer necessary.
19 Therefore, brothers and sisters, since we have confidence to enter the Most Holy Place
by the blood of Jesus, 20 by a new and living way opened for us through the curtain, that is, his body, 21 and since we have a great priest over the house of God, 22 let us draw near to God with a sincere heart and with the full assurance that faith brings,
having our hearts sprinkled to cleanse us from a guilty conscience and having our bodies washed with pure water. 23 Let us hold unswervingly to the hope we profess, for he who promised is faithful. 24 And let us consider how we may spur one another on toward love and good deeds, 25 not giving up meeting together, as some are in the habit of doing, but encouraging one another—and all the more as you see the Day approaching.
Hebrews 12
But you have come to Mount Zion, to the city of the living God, the heavenly Jerusalem. You have come to thousands upon thousands of angels in joyful assembly, 23 to the church of the firstborn, whose names are written in heaven. You have come to God, the Judge of all, to the spirits of the righteous made perfect, 24 to Jesus
the mediator of a new covenant, and to the sprinkled blood that speaks a better word than the blood of Abel.
Hebrews 13
The high priest carries the blood of animals into the Most Holy Place as a sin offering, but the bodies are burned outside the camp. 12 And so
Jesus also suffered outside the city gate to make the people holy through his own blood.
Conclusion: The forgiveness of sins is found only in
the blood of Christ- His life which He gave as a sacrifice for sin.
That is the heart of the Atonement. It is what the New Covenant is found upon His blood/life which was given for our sins. Forgiveness is only found in His blood/life that He gave on our behalf. That is how are sins are removed and taken away. That is what the Law required for sin was the blood of the animal/sacrifice.
hope this helps !!!
