OK, now I understand why Jesus stopped reading at that point, but we must know exactly what "all" refers to.
If ALL refers to ALL PROPHECIES than the Law will be in force until the establishment of the New Heaven and the New Earth, the last one of all prophecies. It would be easier to say "the Law will be in force forever" or "the Law will never be abolished".
When Jesus said "until all is accomplished" He was talking about the law of Moses, so my interpretation is that it would be in effect until all prophecies related to it were fulfilled.
Well Jesus also says this in Luke:
Luke 16:16-17, " 16 “The Law and the Prophets were until John; since then the good news of the kingdom of God is preached, and everyone forces his way into it. 17 But it
is easier for heaven and earth to pass away than for one dot of the Law to become void."
We can see the law is in effect in judgement/in the kingdom:
Revelation 22:14-15, " 14 Blessed [are] they that do his commandments, that they may have right to the tree of life, and may
enter in through the gates into the city. 15 For without [are] dogs, and sorcerers, and whoremongers, and murderers, and idolaters, and whosoever loveth and maketh a lie.
Matt 13:41-43, “The Son of Man will send his angels, and they will
gather out of his kingdom all causes of sin and all law-breakers, and
throw them into the fiery furnace. In that place there will be weeping and gnashing of teeth. Then the righteous will shine like the sun in the kingdom of their Father. He who has ears, let him hear.”
This is after He returns:
Matthew 3:12 His winnowing fork is in His hand to clear His threshing floor and to gather His wheat into the barn; but He will burn up the chaff with unquenchable fire."
Matthew 8:12But the sons of the kingdom will be cast into the outer darkness, where there will be weeping and gnashing of teeth."
Matthew 13:50and throw them into the fiery furnace, where there will be weeping and gnashing of teeth.
Revelation 21:8-9, " 8 But as for the cowardly, the faithless, the detestable, as for murderers, the sexually immoral, sorcerers, idolaters, and all liars, their portion will be in the lake that burns with fire and sulfur, which is the second death.” 9 Then came one of the seven angels who had the seven bowls full of the seven last plagues and spoke to me, saying, “Come, I will show you the Bride, the wife of the Lamb.”
Revelation 20:10-15, " 10 and the devil who had deceived them was thrown into the lake of fire and sulfur where the beast and the false prophet were, and they will be tormented day and night forever and ever. 11 Then I saw a great white throne and him who was seated on it. From his presence earth and sky fled away, and no place was found for them. 12 And I saw the dead, great and small, standing before the throne, and books were opened. Then another book was opened, which is the book of life. And the dead were judged by what was written in the books, according to what they had done. 13 And the sea gave up the dead who were in it, Death and Hades gave up the dead who were in them, and they were judged, each one of them, according to what they had done. 14 Then Death and Hades were thrown into the lake of fire. This is the second death, the lake of fire. 15 And if anyone's name was not found written in the book of life, he was thrown into the lake of fire.
