The Law died on the cross when the veil was torn and the new kingdom covenant began on Pentecost, but the prophecies of the Law and prophets would still be fulfilled.
It does not say that it would "remain in place" until then, it says that everything required in the Law and Prophets must take place to be fulfilled and that Jesus was here to fulfill them and cause them to be fulfilled.
Jesus brought the old covenant to an end when He died.
There wasn't a duel covenant that ran parallel to the new as shown in Galatians 3. (If you believe that, a SDA church is around the corner.)
No one was ever saved by keeping the Law.
Before the Law of Moses came, souls were saved by love, faith, and grace.
But when the Law came, souls were saved by love, faith, and grace.
Then in the new covenant, souls are saved by love, faith, and grace.
Has it really changed that much?
The eternal death, yes.
Since those who are keeping the Law have rejected Jesus and His grace, they will be found lacking. Salvation does not come by the works of the Law of Moses.
Ok, you make a contract for 5 loads of gravel at 10 dollars a load. The man brings 5 loads of gravel and you pay the man 50 dollars. That fulfills the covenant that you made with the man, that ends the agreement.
The next year you go to the man and say I would please like 5 more loads of gravel at 10 dollars a load. But he says that the load of gravel is now 7 dollars a load. Then you might say that you have an agreement for 5 dollars a load.
But the man says that the previous agreement ended when he fulfilled his side of the covenant.
Jesus fulfilled God's side of the covenant on the cross. If you want your gravel, you will have to go into a new covenant with Jesus.
Jesus speaking to Israelites like us, Israelite to Israelite.
We still have the writings of the Israelite Law and Israelite prophets today, so they have not been abolished or disappeared.
The power of the Law covenant was ended at the cross, when Jesus delivered the gravel, died.
Disappear? What does that mean to you? Disappear from all knowledge of men? I mean that the Laws are still readable today, so they still have not "disappeared" even to this day. Could it mean fulfilled? That is, everything must happen to meet the requirements on the Law and prophets?
So that when they are fulfilled, they disappear, as fulfilled?
Do you keep the commands of the Law? Have you set them aside? Do you teach others to keep the Law and the Prophets?
Or have you chosen the new covenant?
Love, faith, and grace....
