Hmm, can it be said the the OT served us with sacrifices to God but the NT serves Christ with us as sacrifices to Him?
In 2 Corinthians 3 Paul differentiates the ministry of death/condemnation and the ministry of the Spirit/righteousness.
For example, the OT approaches the commandments as thou shalt not this, thou shalt not that and thou shalt the other....and leaves each individual to his own shalting or not shalting. Meanwhile, the NT comes from an all encompassing 'love God, love yourself, love your neighbor' and provides muuuch needed help in doing such.
The Glory of the New Covenant
(
Exodus 34:10–35)
7Now if the ministry of death, which was engraved in letters on stone, came with such glory that the Israelites could not gaze at the face of Moses because of its fleeting glory,
8will not the ministry of the Spirit be even more glorious?
9For if the ministry of condemnation was glorious, how much more glorious is the ministry of righteousness!
10Indeed, what was once glorious has no glory now in comparison to the glory that surpasses it.
11For if what was fading away came with glory, how much greater is the glory of that which endures!
However, if you click the available link to Exodus 34:10-35, you will see it take you to the context where "The LORD renews the Covenant" even for them, after new stone tablets were needed, after God reveals His Name, the LORD, with the promise of His Presence, and the 13 attributes of His mercy in 34 vv. 5-7.
So it would seem to me that the exact differentiation between the two, since Moses ministry was indeed glorious in that God Presence was with them but there was something more needed...
The New Covenant
(
Jeremiah 31:26–40)
6Now, however, Jesus has received a much more excellent ministry, just as the covenant He mediates is better and is founded on better promises.
7For if that first covenant had been without fault, no place would have been sought for a second.
8But God found fault with the people and said:
“Behold, the days are coming, declares the Lord,
when I will make a new covenant
with the house of Israel
and with the house of Judah.
9It will not be like the covenant
I made with their fathers
when I took them by the hand
to lead them out of the land of Egypt,
because they did not abide by My covenant,
and I disregarded them,
declares the Lord.
10For this is the covenant I will make
with the house of Israel
after those days,
declares the Lord.
I will put My laws in their minds
and inscribe them on their hearts.
And I will be their God,
and they will be My people.
11No longer will each one teach his neighbor or his brother,
saying, ‘Know the Lord,’
because they will all know Me,
from the least of them to the greatest.
12For I will forgive their iniquities
and will remember their sins no more.”

13By speaking of a new covenant,
c He has made the first one obsolete; and what is obsolete and aging will soon disappear.
I believe this distinction is not only God's Presence with us, manifest in Christ, but also that which gives
us (as a
living sacrifice)
to Him.
